Energy Efficient Precoder Design for Non-Regenerative MIMO-CRN

This letter presents a problem of designing a relay precoding matrix for a multi-input multi-output cognitive relay network, where a secondary system (SS) works in an underlay mode and communicates through a non-regenerative relay. An optimization problem is formulated to maximize the energy efficie...
