全双工MIMO中继系统中基于最大速率的波束成形算法
Maximizing Rate Beamforming for Full-Duplex MIMO Relay System
摘要
Abstract
Full-duplex model can transmit data during one time slot and frequency ,which doubles the transmission data rate of relay systems compared with half-duplex .To improve the transmission rate of full-duplex multi-input and multi-output(MIMO) relay system with amplify-and-forward(AF) strategy , a beamforming scheme of maximizing rate is designed using alternating iterative structure and gradient descent method (GDM ) .We derive the beamforming expressions at relay station ,and design an mini-mum mean square error (MMSE) iterative algorithm as the initial condition .Simulation results reveal that the proposed alternative iterative structure converge quickly and is better than some existing algo-rithm like zero-forcing(ZF) ,minimum mean square error (MMSE) ,maximizing signal-to-leakage-plus-noise ratio(Max-SLNR) algorithm .关键词
