Scheduling diversity outperforms spatial diversity for cooperative multiband spectrum scanning

2015 IEEE International Conference on Consumer Electronics (ICCE), 2015

This paper proposes a wideband spectrum sensing scheme in cooperative cognitive radio networks. The proposed multiband scanning method efficiently exploiting scheduling diversity outperforms the conventional multiband scanning method using the spatial diversity. The proposed scheduling diversity is more beneficial to the low-SNR regime with a large number of sensors and sensing channels.

  • Performance of maximum likelihood detection using antenna diversity technique

    Owing to the forever growing demand for faster data transmission speed in the recent or future telecommunication systems, the multiple antenna systems have been actively investigated and successfully deployed for the emerging broadband wireless access networks (e.g., Mobile WiMAX). Even when a wireless channel with high channel capacity is known, we still require to find superior techniques to achieve high speed data transmission or high reliability. Multiple antenna techniques can be broadly classified into two categories: diversity techniques and spatial-multiplexing techniques. The diversity techniques intend to receive the same information-bearing signals in the multiple antennas or to transmit them from multiple antennas, in so doing improving the transmission consistency. Diversity techniques are used to mitigate degradation in the error performance due to unstable wireless fading channels, for example, subject to the multipath fading etc. A basic idea of the diversity techniques is to convert Rayleigh fading wireless channel into more stable AWGN-like channel without any catastrophic signal fading. When the spatial-multiplexing Techniques are used, the maximum achievable transmission speed can be the same as the capacity of the MIMO channel; however, when the diversity techniques are used, the achievable transmission speed can be much lower than the capacity of the MIMO channel. Spatially multiplexed MIMO (SM- MIMO) systems can transmit data at a higher speed than MIMO systems using antenna diversity. However, spatial demultiplexing or signal detection at the receiver side is a challenging task for SM MIMO systems. This paper addresses the signal detection technique using maximum likelihood detection for SM MIMO systems.

  • Compact scan-phase antenna diversity system for high driving speeds

    A scan-phase diversity system is shown to highly improve the reception quality in Rayleigh-fading scenarios even at high driving speeds. The measurements are conducted with an integrated diversity circuit which enables the phase-aligned signal combination in a die area of only 4mm by 4 mm. Combined with a compact level detection circuit and a micro-controller unit which runs the diversity algorithm the diversity system has a stacked footprint area of 10 cm by 7 cm. Measurement results of test drives using this diversity system in a Rayleigh- fading scenario show a significant reduction of audio mutes compared to a single antenna reference system. This is equivalent to an increased link margin which could also be used for increased audio content or quality from the service provider. The diversity system can be applied at arbitrary driving speeds. A significant improvement of signal quality can be shown for all velocities of at least 100 km/h.

  • Demonstration of OAM-based MIMO FSO link using spatial diversity and MIMO equalization for turbulence mitigation

    We experimentally demonstrate and investigate the performance of a multi- input-multiple-output (MIMO) free-space optical link employing orbital- angular-momentum multiplexing through turbulent channel. We show that turbulence effects can be mitigated by exploiting spatial diversity and MIMO equalization.

  • Software modem for near field acoustic communication with antenna diversity technique

    Acoustic communication has broad utility for near field, device-to-device communication, since it utilizes the standard equipment; speaker and microphone. In this paper, a simple acoustic modem that enables communication using orthogonal frequency division multiplexing (OFDM) is focused on. In near-field acoustic communication, the effect of the environmental noise cannot be negligible. To achieve reliable communication, the modem is designed to use antenna diversity which utilizes multiple microphones. To confirm the effectiveness of the antenna diversity technique, simulation of acoustic communication using real channel data is performed. As a result, it was confirmed that the modem with the antenna diversity technique could achieve lower bit error rate (BER) than that without antenna diversity.

  • Uplink Multiple Base Stations Diversity for UNB based IoT networks

    Ultra-Narrow-Band has been a promising candidate for low-power long-distance transmissions in the context of IoT. Its radio access is random at time and frequency, and can degrade the network performance. We propose to apply signal combining and interference cancellation technologies across multiple base stations in UNB networks, in order to take advantage of their spatial diversity. We evaluate and compare the performance enhancement of each technology, compared to single BS case. These technologies exploiting multi-BS diversity are proved to be significantly beneficial in improving UNB networks' scalability. We can gain until 28 times better performance with one iteration global SIC. We highlight that these results provide us a choice among the technologies according to the improvement needs and the implementation complexity.

  • An adaptive antenna selection scheme for hybrid diversity combining

    Antenna diversity has long been one method of increasing gains and enhancing performance in wireless systems. Such diversity provides a means to overcome the effects of signal multipath and fading in realistic RF channels or propagation environments. The design proposed here uses hybrid combining of two types of antenna diversity, spatial and polarization, to provide a consistently better received RF signal. The design is adaptive in that it periodically tests signal strength on a number of channels, and selects those which provide the best signals at that time. With a four-choose-two system, about 5 dB in power gain over the reference non-hybrid system is achieved. A significant reduction in signal power variance (about 2.3 dB) was also observed experimentally.
