| 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. |
