Joint optimization in MIMO multiple relay channels

YU Fei, YANG Lv-xi (School of Information Science and Engineering, Southeast University, Nanjing 210096, China)  
Joint optimization of cooperative relays in MIMO multiple relay aided communication system is discussed in this paper. A simple linear optimization solution is designed and a multi-user scheduling algorithm is proposed. This new algorithm, which chooses the users with larger cooperation diversity gains from waiting list to serve, can reduce inter-user interference caused by parallel transmission of multiple relays, maintain space diversity introduced by parallel transmission of multiple relays and achieve higher throughput of system.
