SLNR下，信噪比和误码率的关系,比较SLNR和SINR最大的情况，SINR优于SLNR 1~2dB，但SLNR算法的计算量远小于SINR(ZF)-under slnr,the graph between snr and ber.

two-way-relay场景下，中继处理矩阵的设计，仿真分析了DPC-ZF及DPC-MMSE算法的性能要由于AF与ZF算法性能。-In the two-way-relay scenario,simulation show that both DPC-ZF and DPC-MMSE have a higher throughput and lower BER performance compared with the tradition
