摘要研究了N-Nakagami衰落信道上基于多移动中继的译码转发(DF)移动移动(M2M)系统的平均符号差错概率(ASEP)。用矩母函数(MGF)方法求出了各种调制技术的ASEP。然后通过数值仿真对不同条件下的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ASEP性能有重要影响。
ABSTRACT The average symbol error probability (ASEP) of multiple-mobile-relay-based mobile-tomobile (M2M) system with decode-and-forward (DF) relaying over N-Nakagami fading channels is investigated in this paper. The moment generating function (MGF) method is used to obtain the ASEP of various modulation techniques. Then the ASEP performance under different conditions is evaluated through numerical simulations to verify the analysis. The simulation results showed that the fading coefficient, number of cascaded components, relative geometrical gain, power-allocation parameter, and number of mobile relays have an important influence on the ASEP performance.
