Abstract

We present a modified two way relaying method exploiting a maximum ratio transmission. The proposed relaying method attains SNR gain using a maximum ratio transmission, and is feasible to implement in relay systems owing to the absence of need for channel estimation at the relay station. Simulation results show that the modified relaying method provides higher SNR gain than that of a conventional two phase system with multiple antennas.
