摘要：
In this paper an algorithm for joint power control, transmit diversity, and receive beamforming is proposed where transmit diversity, and receive beamforming weight vectors and downlink power allocations are calculated jointly, such that signal to interference ratio at each mobile is above threshold. Since in the frequency, division duplex network uplink and downlink are not reciprocal, transmit diversity, weight vectors are determined using partial phase combining and only few bits are fed back from mobile to base station. It has been shown that this algorithm offers considerable savings in the total transmitted power and significantly, improves the downlink capacity, in a network where only, high data rate users use the proposed algorithm with two antennas at mobile terminal.
