ABSTRACT

ABSTRACT: Abstract - Multiple antennas combined with cooperative relaying, called multiple-input multiple output (MIMO) relay communications, can be used to improve the reliability and capacity of wireless communications systems. A multiuser MIMO FD uplink communication system with an AF relay and precoding matrix design for a multiuser MIMO FD AF relay downlink communication system where users simultaneously transmit data streams to other users via a relay node were considered. Linear precoders are used at the sources and relay, and MMSE combiners are employed at the destinations to reduce the effect of the residual LI. As the corresponding design problem is highly non- convex, a closed-form solution is intractable. Therefore, an iterative method is developed to solve the optimization problem.
