Abstract: For the uplink in CDMA distributed wireless communication system (DWCS) employing the multi-user detection receiver, an antenna dynamic selection algorithm is proposed. As the bit signal-to-interference-plus-noise ratio from a virtual cell arrives at the threshold, antennas are selected dynamically as many as possible to minimize the average power of mobile terminal by getting the trade-off between the increment in the bit signal-to-interference-plus-noise ratio and the increment in the receiver complexity. The simulation shows that the proposed algorithm can achieve almost similar outage capacity as the antenna static selection (ASS) method while the ratio of average power decrement of mobile terminal to average receiver complexity of the proposed algorithm is greater than that of ASS.
