  • Blind adaptive signal reception for MC-CDMA systems with interference suppression

    In this paper we consider signal reception in multicarrier code-division multiple-access (MC-CDMA) systems. A blind adaptive algorithm is proposed to determine a weight vector which optimally combines the desired signal contributions from different carriers as well as suppresses noises and interference. No knowledge of the channel conditions (fading coefficients, signature sequences and timing of interferers, statistics of other noises, etc.), nor any training sequence is required. The performance is examined under Rayleigh fading channels. Results show that the proposed algorithm performs well and is robust to the near-far problem.

  • CDMA cellular mobile system capacity improvement by combination with TDMA and adaptive interference suppression

    This paper proposes a cellular mobile system employing a combination of time division multiple access (TDMA), to multiplex users within a cell, and code division multiple access (CDMA), to control interference between cells. An important aspect of the system design is the use of an adaptive receiver for multiple-access interference suppression. The effectiveness of the adaptive interference suppression is assured by the increased data rate and low spreading ratio afforded by the time division multiplexing of user signals. As a basis for comparison, a model for the reverse channel of the IS-95 cellular CDMA standard has been developed. Both systems were simulated using a multipath fading channel model, with additive white Gaussian noise (AWGN) and multiple access interference. The proposed system is shown to exhibit superior system capacity, and has inherent advantages for system synchronization.

  • A Novel Interference-Avoidance Code Reassignment for Downlink Two-Dimensional-Spread MC-DS-CDMA Systems With Power Control

    In the 2-D time- and frequency-domain spread multicarrier direct-sequenced code-division multiple-access (MC-DS-CDMA) system, maintaining a good code tree structure is the key to controlling the interference level. However, as users come and go, the code tree structure will be fragmented and steeped in a high level of interference. In this situation, an active call may be dropped for not being able to reach a predefined signal quality. To solve this call- dropping problem, we propose a novel code-reassignment strategy to reallocate a low-interferenced code to the could-be-dropped call. This way, not only can this possible call-dropping event be evaded, but also, a low-interferenced 2-D code tree structure can be maintained. The simulation results show that the proposed code-reassignment method can efficiently alleviate the call-dropping problem and boost the call-survival rate simultaneously. It is believed that the proposed scheme fills up an important missing link of the dynamic call- resource management for the 2-D-spread MC-DS-CDMA system.

  • Multiuser Channel Estimation and Tracking for MC-CDMA Uplink Transmissions

    We discuss channel acquisition and tracking in the uplink of a multi-carrier code-division multiple-access (MC-CDMA) system. Channel acquisition is performed jointly with noise power estimation following two different approaches. The first assumes independently faded subcarriers while the second exploits the fading correlation across the signal bandwidth to improve the system performance. Both schemes are based on maximum likelihood (ML) reasoning and exploit some training blocks carrying known symbols. Channel tracking is pursued through least-mean square (LMS) techniques, using data decisions provided by a partial parallel interference cancellation (PPIC) receiver

  • Performance analysis of asynchronous carrier interferometry/MC-CDMA uplink with interference cancellation techniques

    In this paper, we analyze the uplink performance of an asynchronous carrier interferometry/MC-CDMA, with nonlinear parallel and serial interference cancellation techniques. Specifically, we employ the new variant of parallel interference cancellation known as block-PIC and demonstrate significant performance (10 dB) improvement relative to conventional PIC. We also study the effect of order of cancelling in serial interference cancellation by comparing the performance of the conventional fixed ordering scheme with dynamic ordering. We show that dynamic ordering provides a gain of 8 dB relative to fixed ordering.

  • Blind Multiuser Detection Over Highly Dispersive CDMA Channels

    Blind Multiuser Detection Over Highly Dispersive CDMA Channels This paper addresses blind multiuser detection in a direct-sequence code-division multiple-access (DS-CDMA) network in presence of both multiple-access interference and intersymbol interference. In particular, it considers a DS- CDMA system where<tex>$K$</tex>, our<tex>$bar N$</tex>users, are transmitting: the<tex>$bar N$</tex>admissible spreading codes are known and so is the code of the user to be demodulated. The number of interferers, the signatures of a certain number, possible all, of the interferers, and the channel-impulse response of each active user are unknown. The spreading codes of the unknown interferers are determined via a procedure that exploits the knowledge of the set of admissible transmitted codes and of the known active codes. The procedure applies to both single and multiple receiving antennas. The performance assessment of a blind decorrelating detector, implemented by resorting to the proposed identification procedure, shows that it outperforms a plain subspace-based blind decorrelator for small sizes of the estimation sample.

  • Research of long-term and short-term average performance in TD-SCDMA system link simulation

    In order to improve the research of TD-SCDMA system key techniques and provide necessary results for system level performance investigation, long-term and short-term average performance in link simulation is researched and compared. According to the TD-SCDMA protocols, a link simulation platform is set up using many important algorithms including channel estimation, joint detection, soft decision Viterbi decoding and so on. The emphasis is to evaluate the link level performance of DPCH 12.2 kbps under various multi-path fading channel environments.

  • Performance analysis of Volterra-based nonlinear blind multiuser detector for DS-CDMA systems

    Multiuser detection is an effective method to suppress the multiple access interference (MAI) and improve the performance of direct sequence code division multiple access (DS-CDMA) communication systems. Since the optimum decision boundary is nonlinear structure in the optimum multiuser detector can improve the performance of the receiver. The authors of this paper have proposed two nonlinear blind adaptive interference cancellation algorithms (the exact Newton and the approximate Newton) in one of their earlier works [Guo Linlin and Sadasivan,P.K., Sept. 2002]. In this paper, a complete performance analysis and characterization of the nonlinear schemes with respect to various asynchronous parameters are investigated in both synchronous and asynchronous DS-CDMA systems. The numerical results show that the adaptive blind multi-user detectors yield significant bit-error-rate (BER) improvement over the conventional matched filter detector in the presence of strong MAI. Further, the two nonlinear adaptive algorithms outperform the linear algorithm due to the nonlinear nature of the transmitted signals. Most attractively, the approximate Newton algorithm offers lower computational complexity, higher numerical stability and similar BER performance in comparison to the exact Newton algorithm.
