摘要:

文章基于N-Rayleigh衰落信道,研究了固定增益放大转发(Fixed-gain Amplify-and-forward,FAF)协作车--车通信系统的平均符号误码率(Average Symbol Error Probability,ASEP)性能.文章首先基于矩生成函数(Moment Generating Function,MGF)的方法,分别推导了车--车间无线通信系统(Inter Vehicle Communication Systems,IVC)采用相移键控调制(Phase Shift Keying,PSK),正交幅度调制(Quadrature Amplitude Modulation,QAM),脉冲幅度调制(Pulse Amplitude Modulation,PAM)等相干检测调制方式下的ASEP的精确表达式.然后对不同通信系统条件下ASEP性能做了数值仿真,使理论分析结果得到了验证.仿真结果表明,随着中继车辆节点数的增加,系统的ASEP性能得到了良好的改善.

Abstract:

The average symbol error probability (ASEP) performance of vehicle-to-vehicle communication system with fixed-gain amplify-and-forward (FAF) relaying over N-Rayleigh fading channels is investigated in this paper. Based on the moment generating function (MGF) approach, the exact ASEP expressions are derived for several modulation schemes, including phase shift keying (PSK), quadrature amplitude modulation (QAM), and pulse amplitude modulation (PAM). Then the ASEP performance under different conditions is evaluated through numerical simulations, and the accuracy of the analytical results is verified. The simulation results show that the ASEP performance can be improved with the increase of the number of relayed vehicular.
