Abstract: The wireless cellular communications is currently undergoing rapid growth. The conventional cellular system is not able to cope with the increasing demands. A new cellular system (distributed wireless systems) is needed to provide a high data rate to accommodate the new video and data services. Distributed wireless system is a one of the Multi-Input-Multi-output (MIMO) system. The transceiver strategy of a single user communicate with the systems is the transmit diversity scheme with the distributed antennas. For this closed-loop transmit (Tx) diversity, Tx weights vectors are found base on the Rayleigh Fading Channel which is known at the receiver. By assuming the closed-loop feedback information is reliable. The performance of the system is linearly increases as the distributed antennas used. In this project, the optimal weights vectors are founded and the performance is analyzed. The results shows that distributed wireless transmit diversity scheme is more accurate than the nondistributed one. Besides, several transmission schemes based on the distributed cellular system structure were simulated, and the performances were analyzed.
