Physical-layer network coding (PNC) and orthogonal frequency division multiplexing (OFDM) are applied to two-way wireless relay channel. Signals transmitted from two stations simultaneously are synthesized at the relay station in multiple access (MA) link on the two-way relay channel. Precoding at the sending stations is required to compensate multipath fading for each signal. In this manuscript, precoding only with channel phase synchronization is proposed assuming that maximum a posteriori probability (MAP) decoding is applied at the relay node and the channel capacity in MA link is considered to be evaluated. |
