Abstract: Inter-symbol-Interference (ISI) caused by multipath propagation has made high speed broadband communication a backbreaking task. Time reversal transmission method makes use of the behaviour of multipath environment by converging energy in the temporal and spatial domains. In this paper, a wireless channel access method named time reversal division multiple access (TRDMA) is being proposed. The system performances with multiple-transmit-antenna scheme using TRDMA is investigated in terms of the bit-error-rate, the effective signal-to-interference-plus-noise-ratio, the achievable sum rate and the outage probability. Also, the bit error rate improvement over code division multiple access method (CDMA) is also evaluated. Satisfying simulation results are obtained using the multiuser downlink systems of the proposed method which makes it a high speed broadband wireless communication method in the future.
