【 摘 要 】

Inter-symbol-interference (ISI) has become one of the major obstacle in achieving high speed and high capacity wireless communication. In this paper, we propose a time reversal transmission method which converges energy both in spatial and temporal domains and thereby reduces ISI. The system performances of multiple transmit antenna schemes using Time Reversal Division Multiple Access (TRDMA) is evaluated in terms of effective signal-tointerference- plus-noise-ratio and achievable sum rate .Also the bit error rate of TRDMA over Code division Multiple Access and the impact of modulation schemes on effective SINR is investigated. Simulation results obtained using multiuser downlink systems makes it a high speed wireless transmission method in the future.
