Abstract

This paper considers a multiple-input multiple-output (MIMO) relay system with an energy harvesting relay node powered by harvesting energy from the source node using power splitting (PS). The rate maximization problem subject to power constraints at both the source and relay nodes is considered for two different scenarios. Firstly, the relay matrix and PS ratio are jointly optimized with uniform source precoding and then in the second scenario the source covariance is optimized as well. Iterative approaches and dual decomposition are proposed based on the structures of the optimal relay and source covariance matrices for the scenarios.
