Particle Swarm Optimization for Weighted Sum Rate Maximization in MIMO Broadcast Channels

4 Aug 2015Tung T. VuHa Hoang KhaTrung Q. DuongNguyen-Son Vo

In this paper, we investigate the downlink multiple-input-multipleoutput (MIMO) broadcast channels in which a base transceiver station (BTS) broadcasts multiple data streams to K MIMO mobile stations (MSs) simultaneously. In order to maximize the weighted sum-rate (WSR) of the system subject to the transmitted power constraint, the design problem is to find the pre-coding matrices at BTS and the decoding matrices at MSs...
