摘要: 针对采用改进DNF(denoise-and-forward)方案的Two-way中继系统,提出一种满足匹配性的调制映射方案,进一步提高了DNF方案的BER(bit error rate)性能,并给出BER的计算方法.仿真结果验证了BER计算方法的正确性,以及满足匹配性的调制映射方案的有效性.

Abstract: We propose a modulation mapping scheme for matching the two-way relay systems with the improved DNF (denoise-and-forward) scheme, which significantly improves the BER(bit error rate) performance of DNF scheme. We also propose a BER calculation method. Simulation results show that the proposed method for the BER calculation is proper and the proposed modulation mapping scheme is effective.

Key words: two-way relay, denoise-and-forward, denoise mapping, modulation mapping
