Abstract

Multi-user precoding in multi-relay systems is investigated in this paper. Firstly, a distributed precoder through the relay nodes is presented, which performs as a sub-optimum solution in terms of both the outage probability and ergodic capacity. Then, a multi-user precoder at the source node is jointly designed, where is used to enhance the maximum signalto-leakage-and-noise ratio of each data stream.

Keywords: relay mimo multi-user precoding
