N2 - Recently two-way relaying has become a promising protocol. The design of the processing matrix of the two-way relay channel is of significant importance since it could dramatically influence the system performance. In this paper, we propose a nonlinear design of the relay processing matrix with dirty paper coding (DPC). And compared with the traditional linear schemes, it could amplify the useful signal and mitigate the impact of interference and noise. Moreover, the multi-user scenario, which is more common in the practice, is also taken into consideration. And based on different receive criterions DPC-ZF algorithm and DPC-MMSE algorithm are proposed. Simulation results show that both DPC-ZF and DPC-MMSE have a higher throughput and lower bit error ratio (BER) performance compared with the traditional AF algorithm and zero-forcing (ZF) algorithm.
