Efficiency Enhancement of RF-Pilot-Based Phase Noise Compensation for Coherent Optical OFDM Systems

OFDM 2012; 17th International OFDM Workshop 2012 (InOWo'12), 2012

Phase noise effects must be taken into account when studying the performance of coherent optical orthogonal frequency division multiplexing (CO-OFDM) transmission systems. One drawback of CO-OFDM is the high sensitivity to phase noise. In this paper, we explain different kinds of phase noise effects on the OFDM signals and analyze the phase noise effect induced by transmitter laser and receiver ...


CPW-OFDM(Cyclic Postfix Windowing OFDM) for the B5G (Beyond 5th Generation) Waveform

2018 IEEE 10th Latin-American Conference on Communications (LATINCOM), 2018

For the new radio waveform of the beyond 5G mobile system, the spectrum efficiency is the most important factor. Especially, OOB (out-of-band) power spectrum must be reduced to increase the spectrum efficiency and to save the frequency resources. Filtering is the one way to get the sharp OOB spectrum. So, f-OFDM (filtered orthogonal frequency division multiplexing), UFMC (universal filtered multicarrier) ...

  • Efficiency Enhancement of RF-Pilot-Based Phase Noise Compensation for Coherent Optical OFDM Systems

    Phase noise effects must be taken into account when studying the performance of coherent optical orthogonal frequency division multiplexing (CO-OFDM) transmission systems. One drawback of CO-OFDM is the high sensitivity to phase noise. In this paper, we explain different kinds of phase noise effects on the OFDM signals and analyze the phase noise effect induced by transmitter laser and receiver local oscillator. We review the pilot-aided and the standard RF- pilot (RFP) based phase noise compensation methods and explain its drawbacks. We provide two extended RFP schemes that overcome the drawbacks of the standard RFP scheme and enhance the performance of CO-OFDM systems. A simulation results of a CO-OFDM transmission system with 4-QAM is simulated. Furthermore, the phase noise effects for various laser linewidths on the system performance is presented. Index terms - CO-OFDM, phase noise, phase estimation, quadrature ampltiude modulation (QAM).

  • CPW-OFDM(Cyclic Postfix Windowing OFDM) for the B5G (Beyond 5th Generation) Waveform

    For the new radio waveform of the beyond 5G mobile system, the spectrum efficiency is the most important factor. Especially, OOB (out-of-band) power spectrum must be reduced to increase the spectrum efficiency and to save the frequency resources. Filtering is the one way to get the sharp OOB spectrum. So, f-OFDM (filtered orthogonal frequency division multiplexing), UFMC (universal filtered multicarrier) and FBMC (filter bank multicarrier) belong to the filtering method and were suggested as 5G new radio waveform. However, there are still some problems such as the very complicated process and some difficulty to the realization. The other approach is the windowing method. WOLA-OFDM (weighted overlap and add - orthogonal frequency division multiplexing) system is the most representative windowing method. However, the WOLA-OFDM system has inherently some serious problem. Due to the overlap process of the copied and added extensions, the left extension part will invade into the right part of the previous OFDM symbol because left extension and right extension of two consecutive OFDM symbols must be overlapped in order not to sacrifice the time resource. This is very serious data collision in the transmitter even before the transmission. So, in order to improve the WOLA-OFDM system and to solve this data collision problem of WOLA-OFDM between the consecutive OFDM symbols, we like to propose a CPW-OFDM (cyclic postfix windowing - orthogonal frequency division multiplexing). In this proposed CPW- OFDM system, the first part of the OFDM symbol is copied and added on the right-end of the OFDM, which is the cyclic postfix. Then, windowing is made on this cyclic postfix and already existing cyclic postfix. WOLA-OFDM has right and left extensions and windowing is performed on these 2 extensions, but the proposed CPW-OFDM has only one extension on the right side and windowing is perform and on this right extension and left part of CP(cyclic prefix). Therefore, there is no data collision in the proposed CPW-OFDM. CPW-OFDM system is an improved and simplified version of the WOLA-OFDM system. Simulations results show that the proposed CPW-OFDM system has comparable OOB spectrum reduction characteristics and can be designed by simple some modification from the conventional OFDM system.

  • Performance comparison of visible light communication systems based on ACO-OFDM, DCO-OFDM and ADO-OFDM

    We compared the performance of the asymmetric and direct current bias limiting optical orthogonal frequency division multiplexing (ADO-OFDM), asymmetric limiting optical orthogonal frequency division multiplexing (ACO-OFDM), and the direct current bias limiting optical orthogonal frequency division multiplexing (DCO-OFDM) in visible light communication (VLC) systems. We optimize the power ratio between ACO and DCO parts in ADO-OFDM. The results show that ADO-OFDM has better performance than DCO-OFDM at small bias value, which indicate higher power spectral efficiency. It is also shown that the BER of ACO-OFDM with 16-QAM format is smaller than that of ADO-OFDM with 4-QAM format.

This algorithm has been implemented in our software-based DVB-T2 receiver.

  • An OFDM WLAN Multicast Hybrid Erasure Correction Prototype with Feedback Aggregation and Rate Adaptation

    Aggregation of multicast feedback in time is evaluated herein with respect to physical layer rate adaptation in OFDM based WLANs. An opportunistic scheduler with perfect channel knowledge is used as an upper limit for multicast throughput. We find that feedback aggregation multicast performs close to this limit. In realistic fading scenarios, delay constrained audio-visual streaming performance of a hybrid overlay FEC prototype implementation - including feedback aggregation and rate adaptation - is evaluated by simulation. In this context, a popular unicast rate adaptation mechanism is extended to multicast streaming, and its residual error performance is improved significantly by simple means.

  • Notice of Violation of IEEE Publication Principles<br>Analysis of ACO-OFDM, DCO-OFDM and Flip-OFDM for IM/DD optical-wireless and optical-fiber system

    The three types of orthogonal frequency division multiplexing techniques named Asymmetrically-clipped Optical OFDM (ACO-OFDM), DC biased Optical OFDM (DCO- OFDM) and Flip-OFDM systems are analyzed and compared in optical wireless and optical fiber system. Data are taken using MATLAB and the simulation software called Optisystem 13. The techniques are compared in terms of their bit error rate (BER) with respect to electrical energy to the noise power ratio (Eb/N0) in presence of additive white Gaussian noise in case of optical wireless channel and by thermal noise in case of optical fiber channel. Different forms of Quadrature Amplitude modulation (QAM) have been used for modulating the OFDM signal such as 4-, 16-, 64 and 256-QAMs. After the final analysis, it is seen that ACO-OFDM requires a lower power to reach the target BER of 10-4 compared to DCO-OFDM and Flip-OFDM in both optical wireless and fiber channels. In the last part, the three bipolar OFDM systems are analyzed by observing their receiver sensitivity using PIN photodiode in 25 km optical fiber channel. The result shows that ACO-OFDM has a better sensitivity than DCO-OFDM and Flip-OFDM.

  • Comparison of ACO-OFDM, DCO-OFDM and ADO-OFDM in IM/DD Systems

    In this paper, three forms of orthogonal frequency division multiplexing (OFDM) designed for intensity modulated/direct detection (IM/DD) optical systems are compared. These are asymmetrically clipped optical OFDM (ACO- OFDM), DC biased optical OFDM (DCO-OFDM) and asymmetrically clipped DC biased optical OFDM (ADO-OFDM). ADO-OFDM is a new technique that combines aspects of ACO-OFDM and DCO-OFDM by simultaneously transmitting ACO-OFDM on the odd subcarriers and DCO-OFDM on the even subcarriers. The odd subcarriers are demodulated as in a conventional ACO-OFDM receiver and the even subcarriers are demodulated using a form of interference cancellation. ADO-OFDM is shown to be more optically power efficient than conventional ACO-OFDM and DCO-OFDM, for some bit rate/normalized bandwidths. It is also shown that by varying the proportion of optical power on the ACO-OFDM component, the DC bias level of DCO-OFDM and the constellations sent on the odd and even subcarriers, the optical power efficiency of ADO-OFDM can be changed.

  • Performance analysis of direct detection Flip-OFDM for VLC system

    In recent years researchers have shown that Orthogonal frequency division multiplexing (OFDM) is also a promising technology for optical wireless communications (OWC). In this paper we evaluate the performance of direct detection Flip-OFDM with different mapping schemes in indoor OWC, visible light communication (VLC). Three OFDM techniques, namely, DC-clipped optical OFDM (DCO-OFDM), asymmetrically clipped optical OFDM (ACO-OFDM) and flip OFDM are discussed. The performance of M-QAM and M-PSK mapping schemes in Flip-OFDM are studied using simulation results.

  • A comprehensive study of universal time-domain windowed OFDM-based LTE downlink system

    For the 5G system and beyond, several new-waveforms with low out-of-band emission (OOBE) have been proposed to improve spectral efficiency. The universal timedomain windowed OFDM (UTW-OFDM) have been proposed as a waveform that has the low OOBE characteristics and high compatibility with the conventional cyclic prefix OFDM (CP-OFDM)-based systems. To indicate the feasibility of the UTW-OFDM-based system in the 5G and beyond, the comprehensive evaluation of the UTW-OFDM-based LTE system is important, however, the evaluation of the UTW-OFDM-based LTE system complexity has been not reported. Furthermore, the communication quality of the UTW-OFDM-based LTE system was evaluated by using BER characteristics on the short delay multipath propagation channel in the previous studies. In this paper, to show the feasibility of the UTW-OFDM for the 5G and beyond, the complexity of the UTW- OFDM-based LTE downlink (DL) system is evaluated and compared with one of the LTE-DL system with the conventional CP-OFDM and the filtering-based waveform (UF-OFDM). The complexity of the conventional CP-OFDM-based system and the UTW-OFDM-based system is about 0.45 % of the complexity of the UF-OFDM-based system. Furthermore, the communication quality of the UTW-OFDM-based LTE-DL system is evaluated by using BLER on the 3GPP Extended Typical Urban (ETU) channel model with the 70 Hz Doppler shift. The UTW-OFDM-based LTE-DL system can improve the OOBE of the conventional CP-OFDM-based LTE-DL system by 45 dB with only 2.0 dB deterioration of EN<sub>0</sub> to achieve BLER = 10<sup>-1</sup> even if the 64QAM is applied with a half coding rate.

  • Performance analysis of adaptive channel estimation for U-OFDM indoor visible light communication

    The paper presents a performance analysis for optical in-door communication system based on orthogonal frequency division multiplexing (OFDM) modulation with adaptive channel estimation. Modulation parameters will be adapted to meet the optical domain circumstances mainly the non-availability of bipolar signals. Three schemes to come over the bipolarity issues are available. Asymmetrical clipped optical OFDM (ACO-OFDM), DC Biased optical-OFDM DCO-OFDM and unipolar OFDM (U-OFDM). Paper considers the use U-OFDM because it provides a best performance. The adaptive channel estimation is applied, since the moving receiver doesn't know the channel. LS (least square) and block-type pilot are used in the proposed simulation. And finally to show the effect of changing the receiver position on the BER performance for different constellation order.
