已经示出，其中散射在发射机和接收机周围的移动到移动的（M2M）通信可能经历比固定到移动的（F2 M）通信更严重的信道衰落。采用双Nakagami-m衰落来提供M2M信道的真实描述。通过使用矩生成函数（MGF）为基础的方法，精确的符号错误率（SER）的表达式，它可以数值计算，推导出所考虑的移动中继为基础的M2M系统。此外，渐近SER界提供了在高信噪比制度的洞察力，我们的方法。根据我们的分析，在独立同分布（i.i.d）信道的情况下，可以获得2 × min（m1，m2）的渐近分集阶数。数值研究表明，解析结果完全符合模拟。
It has been shown that mobile-to-mobile (M2M) communications, where scatters are both around the transmitter and the receiver, may experience more severe channel fading than the fixed-to-mobile (F2M) communications. Double Nakagami-m fading is adopted to provide a realistic description of the M2M channel. By using the moment generating function (MGF) based approach, the exact symbol error rate (SER) expression, which can be numerically evaluated, is derived for the considered mobile-relay-based M2M system. Moreover, the asymptotic SER bound is provided at a high SNR regime for the insight of our approach. According to our analysis, an asymptotic diversity order of 2 × min(m1, m2) can be achieved in case of independent identically distributed (i.i.d) channels. Numerical studies illustrate that analytic results exactly match the simulations.
