Two-way relay networks based on product relay

Two-way relay networks in additive white Gaussian noise channels are studied. A novel scheme based on the product relay is proposed and the whole block diagram is obtained. Furthermore, the presented analysis shows that the proposed scheme outperforms the traditional amplify-and-forward relay. Two-way relay networks based on the product relay provide a better bit error ratio performance in high signal-to-noise ratio regions, which is consistent with the simulation result.
