Generalized Schur Decomposition-Based Two-Way Relaying for Wireless MIMO Systems

Deploying relay stations improves the Signal-to-Interference and Noise Ratio (SINR) by making a Pico cell environment. Nonetheless, a critical problem associated with deploying RS is additional resource consumption, which reduces the actual transmission rate. Two-way relaying schemes that use Physical layer Network Coding (PNC) reduce the additional resource consumption and thereby improve the transmission rate. In this paper, they propose a novel two-way relaying scheme for coded Multiple-Input Multiple-Output (MIMO) systems. The proposed scheme involves generalized Schur decomposition-based precoding and Successive Interference Cancellation (SIC).
