| 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. |
