In this paper, we propose a fast converging multiuser detection for interleave-division multiple access (IDMA) system based on time-reversal (TR) technique. The proposed algorithm uses the time-reversed version of the channel impulse responses (TR-CIR) obtained from the uplink to process the received signal before the elementary signal estimator (ESE). With the help of the weak correlation of fading channel for difference user end (UE), the signal to interference and noise ratio (SINR) at the… CONTINUE READING
