联合功率分配的全双工MIMO中继最小速率优化
Minimum rate optimization with joint power allocation for full-duplex MIMO relay
摘要
Abstract
This paper aims at maximizing the end-to-end rate of the full-duplex Multiple-Input Multiple-Output (MIMO) relay system suffering from channel estimation errors and the limited dynamic range (LDR) of electronic components in the RF chain. The problem of rate maximization is formulated as a weighted sum-rate optimization problem and we propose a joint power allocation (JPA) algorithm to solve it.Allowing the system to allocate power based on the channel state information (CSI),JPA is able to jointly optimize the pre-coding matrices of the source node and the relay node.Simulation results reveal that the JPA algorithm outperforms the traditional algorithms associated with individual power constraints.关键词
