摘要

Virtual uplink beamforming and power control technique (V-UBPCT) is an effective means for improving downlink performance in DS-CDMA systems. We present a modified V-UBPCT algorithm for block space-time coding scheme with two array antennas, in which the downlink beamforming weight and transmitted power vectors are generated iteratively when the total transmitted power is minimized while received signal-to-interference-and-noise (SINR) requirements are maintained. Simulations compare the total transmitted power and SINR between conventional orthogonal space-time coding scheme and our method.
