Abstract

Abstract

The channel feedback requirement of the MISO-SDMA using Zero-Forcing (ZF) precoding in multi- antenna broadcast channels can be considerably reduced by employing more antennas at user terminals and using the related antenna combining technique. In this paper, a combining scheme based on SINR maximization is proposed to jointly design the optimal combining vector and the quantization of the effective channel vector. Different from the existing combining schemes, the proposed scheme takes into account of both the effective received SNR and the inter-user interferences from the channel quantization. Also, the existing schemes of MRC and quantization-based combining (QBC) are proved that the particular cases if the SNR tends to zero and to infinite, respectively. Simulation results show that the proposed scheme outperforms the above two algorithms in terms of sum capacity, with the same feedback bits.
