全双工MIMO中继系统高性能的波束成型算法
A high-performance beamforming scheme for full duplex MIMO relays
摘要
Abstract
Full-duplex systems perform simultaneous transmission and reception in the same frequency band,hence promising up to twice the data rate offered by half-duplex systems.However,in full-duplex systems,self-interference at the relay,due to the signal leakage from its transmitter to receiver,will lead to a significant degradation of the system performance.Therefore,one of the key challenges in full-duplex relaying systems is how to manage and control self-interference efficiently.In order to suppress the self-interference from relay transmission to relay reception and improve the transmission rate,a new beamforming combination method is proposed for full-duplex Multiple Input Multiple Output(MIMO) relaying system.This method consists of Singular Value Decomposition(SVD) beamforming at source and destination node,Maximum Signal to Interference plus Noise Ratio(Max-SINR) receive beamforming,and transmit beamforming Maximum Signal to Leakage plus Noise Ratio(Max-SLNR) at relay station,respectively.Then,an iterative structure between Max-SINR and Max-SLNR is introduced to optimize the beamforming matrix at the relay jointly.Simulation results show the proposed method performs better than the existing beamforming schemes as the Interference to Noise Rate(INR) decreases.关键词
