基于离散粒子群优化的多用户MIMO用户选择
Discrete PSO user selection for multiuser MIMO systems
摘要
Abstract
In order to decrease computation complexity as well as maintain good performance, this paper studied a user selec-tion method for multiuser MIMO based on discrete particle swarm optimization (PSO). The proposed user selection method based on sum-MSE precoding. It showed that with this method, it could support as many users as long as the number of total substreams was no bigger than the transmit antenna number. When the user had less substreams than receive antennas, if could support more users than BD based user selection methods and achieved larger sum rate. Simulation results indicate that this method can obtain a flexible tradeoff between computation complexity and system performance.关键词
