In this paper, a space-time trellis-coded (STTC) multi-carrier code-division multiple-access (MC-CDMA) system for different states in multi-path fading channel is proposed, and the performance of the system is evaluated using simulation. The corresponding bit error rate (BER) is obtained using minimum mean-square error (MMSE), maximum-ratio combining (MRC), and equal-gain combining (EGC) receivers...
This paper discusses the performance analysis of multi-antennas systems with receive antenna selection over quasistatic fading channels. In performing the analysis with antenna selection, the selection criterion adopted is based on selecting best Nr antennas out of the available NR receive antennas such that the instantaneous signal-to-noise ratio (SNR) at the receiver is maximized. It is assumed...
Cellular communication systems need to support simultaneous transmission of multiple data rates over the same medium. A major aspect of design of cellular systems is simultaneous sharing of channel resources avoiding multiple access interference between users. For high quality communication this must be done without severe degradation in performance of the system. Orthogonal frequency division multiple...
