| 摘 要： | 在n-Rayleigh信道下，研究了使用最大比合并接收的移动车-车通信系统的平均符号误码率和中断概率性能. 基于特征函数方法，推导了移动车-车通信系统在n-Rayleigh衰落信道上采用相移键控调制、正交幅度调制、脉冲幅度调制等方式的平均符号误码率的精确表达式和近似表达式，同时用近似闭合表达式表示中断概率. 然后通过数值仿真，验证理论分析的有效性. 仿真结果表明，系统的性能可以通过增加分集支路数以及减小衰弱因子来改善.

| Abstract: | Average symbol error probability (ASEP) and outage probability (OP) of
vehicle-to-vehicle mobile communication system using maximal ratio combining (MRC)
under n-Rayleigh fading channels is investigated. With the characteristic function (CHF)
method, exact and approximate ASEP expressions are derived for shift keying modulation
(PSK), quadrature amplitude modulation (QAM), and pulse amplitude modulation
(PAM). Closed form approximate OP expressions are presented. Simulation results shows
validity of the theoretical analysis, and improvement of the system performance with increased
diversity branches and decreased fading factor. |
