Joint Source-Relay Optimization for Fixed Receivers in Multi-Antenna Multi-Relay Networks

We jointly optimize the source and relay precoders for multi-antenna multi-relay networks employing a prefixed receiver. Prefixed receivers are of practical interest since they enable low complexity at the end-user's receiver as well as backward compatibility. To compute the source and relay pr...
