研究了N-Nakagami衰落信道上基于多移动中继的解码转发(DF)移动到移动(M2M)网络的中断概率(OP)和平均符号差错概率(ASEP)性能。功率分配问题是为了确定应如何在广播和中继阶段之间共享总发射功率以实现性能优化而制定的。然后通过数值仿真对不同条件下的OP和ASEP性能进行了评估，以验证分析的正确性。仿真结果表明，衰落系数、级联分量数、相对几何增益、功率分配参数和移动中继个数对OP和ASEP性能有重要影响。
The outage probability (OP) and average symbol error probability (ASEP) performance of multiple-mobile-relay-based mobile-to-mobile (M2M) networks with decode-and-forward (DF) relaying over N-Nakagami fading channels is investigated in this paper. The power allocation problem is formulated to determine how the overall transmit power should be shared between broadcasting and relaying phases for performance optimization. Then the OP and ASEP performance under different conditions is evaluated through numerical simulations to verify the analysis. The simulation results show that the fading coefficient, the number of cascaded components, the relative geometrical gain, the power-allocation parameter, and the number of mobile relays have an important influence on the OP and ASEP performance.
