Abstract :
Two-way relaying via the amplify-and-forward technique has received much recent attention. A modulo-and-forward (MF) variant of it has recently been proposed for single-antenna transmission, which can significantly reduce the peak and average relay transmission powers. The present work considers two-way relaying for multi-input multi-output (MIMO) signal transmission. We propose an MF technique for Alamouti space-time coding and spatial multiplexing. Simulation results confirm the advantage of the proposed technique in enhancing the peak and average power efficiency of the relay.
