| 摘 要： | 现实的无线通信环境不仅存在着高斯白噪声干扰,而且存在着随机冲击干扰。采用高斯混合噪声的模型,对存在冲击噪声干扰的Rayleigh信道应用选择式合并分集接收,并对MPSK系统的误码率性能做了研究和分析。仿真结果显示了系统性能与随机冲击干扰的关系,同时也证明了SC分集接收是改善无线通信系统的性能的一项有效技术。

| Abstract: | There are both additive white Gaussian noise (AWGN) and random impulsive noise in realistic wireless communication channels. Here we analyze the BER performance of MPSK system using SC diversity combining in Rayleigh fading channel with the Gaussian-mixture model. The simulation results show the relationship between the attributes of impulsive noise and the system performance. We can also see that SC is an effective technique to improve the system performance in wireless communication systems. |
