Precoder Design for Multi-Hop Cognitive MIMO Relay Systems With Finite-Alphabet Inputs

This paper investigates the precoder design in a multi-hop multiple-input multiple-output (MIMO) relay system with cognitive radio. We assume that the source node (secondary user) sends data to the destination node (secondary user) by means of multiple relay nodes (secondary users), and that the sou...
