520 $a Though the information capacity of wireless communications systems increases dramatically by employing multiple transmit and receive antennas, increasing the signal quality or reducing the effective error rate is still a challenging issue becaus
520 $a However, wideband high data rate transmission may lead to severe frequency-selective channel fading that causes intersymbol interference (ISI) and corrupts the received signal. Furthermore, in an environment with several cochannel users, there e
520 $a The dissertation is concerned with the problem of interference mitigation and performance enhancement in an STTD system. Different solutions are proposed depending on the type of system under study and the amount of knowledge available about the
520 $a By exploiting the spatial and temporal structure of STBC, a novel scheme is presented first to suppress ISI, coherently demodulate the information symbols with estimated CSI.
520 $a Considering an environment with several cochannel users, a method for solving this in a joint fashion is suggested based on maximum likelihood (ML) estimating. It is shown that how a combined transmit diversity, equalization and CCI suppression
520 $a Adaptive space-time transmit diversity (ASTTD) is proposed as a closed-loop approach for further performance enhancement, which combines the ordinary STTD scheme with simpler feedback information. This scheme is easy to be included in the curren
520 $a The performances of the proposed methods are evaluated by theoretical analysis and numerical simulations, and compared favorably with other alternative methods. It is demonstrated that an STTD system, both open-loop and closed-loop, is extremely
