摘要:The multiuser multiple input multiple output (MU-MIMO) proficiency is practicable to significantly improve the diversity and multiplexing gain in emerging wireless networks. Physical-layer network coding (PNC) can efficiently manage and improve the utilization of available spectrum. To resolve the data reliability and diversity gain, a kind of combination called Vertical-Bell Laboratories Layered Space-Time (V-BLAST) and PNC has brought forth a V-BLAST with PNC (V-BLAST-PNC) strategy to enhance the throughput and the performance of emerging wireless networks. We propose a novel cross-layer V-BLAST-based PNC scheme to avail the diversity in multiplexing gain by packet redundancy. The redundancy is introduced to improve the throughput and energy efficiency performance in MU-MIMO by avoiding the packets retransmissions at an upper layer. Experimental evaluation is based on BPSK/QPSK modulation over flat fading channels with the zero forcing and minimum mean square error equalizers. Based on simulation results, we conclude that the proposed V-BLAST-PNC scheme has fewer packets retransmissions and better throughput when compared with the state-of-the-art traditional solutions.
