| Abstract: | The performance of amplify-and-forward based two-way relay network is analyzed in combina-tion with energy harvesting technology. According to the end-to-end signal-to-noise ratio( SNR) balan-cing criterion,the optimal power allocation of two sources and the optimal energy harvesting proportion of the single selected relay are derived. Simulation results show that the proposed method can achieve the best performance. Comparison shows that energy harvesting two-way relay communication network has a higher achievable transmission rate than conventional two-way relay network. |
