... approach the optimal BER performance given by the MFB. More- over, for large N, the proposed system can ever outper- form the theoretical QPSK BER performance. Because the proposed system can acquire ... technique for multi-carrier CDMA (MC-CDMA) systems. In the literature, conven- tional MC-CDMA systems, such as the Walsh-Hada- mard (WH) MC-CDMA system, experience limited uplink performance because ... can enhance system performance and outperform the con- ventional STBC MISO and MIMO systems. The rest of this article is organized as follows. In Sec- tion 2, we pre sent the SISO system block...

... Q-OFDMA systems with smaller P have better BER performance; while with SNR increasing, Q-OFDMA systems with larger P will become superior. The exact SNR point where one system starts to outperform ... square error (MMSE) equalizer is used, for BPSK modulated signals, Q-OFDMA system is always better than OFDMA system with ZF equalizer (for conventional OFDMA systems, ZF is already the maximum likelihood ... improve the performance of Q- OFDMA systems by suppressing the noise enhancement effect. While for general OFDMA systems, it is known that MMSE equalizer almost has the same performance as ZF equalizer. Figure...

This motivates an approximated power control feasibility condition (PCFC) proposed for admission control of a multiple antenna ... overall system throughput. In this paper, we propose a cross-layer AC policy combined with an ARQ-based ROP algorithm for a CDMA beamform- ing system. Both optimal and suboptimal admission control policies...
