| 摘 要： | 本文研究高效频谱调制方式ＭＰＳＫ及ＭＱＡＭ在蜂窝移动通信中的应用及其性能。在综合考虑共道干扰，Ｒａｙｌｅｉｇｈ衰落以及高斯噪声等影响因素的基础上，结合分集接收技术，我们给出了ＭＰＳＫ及ＭＱＡＭ应用于蜂窝移动通信时误码率计算的通用近似公式。蒙特－卡洛仿真表明文中给出的误码率近似公式能很好地吻合实际系统的仿真结果。

| Abstract: | In this paper, we investigate the performance of two families of spectrally efficient modulation schemes, M PSK and M QAM, for cellular mobile systems. The effects of the presence of co channel interference (CCI) in Rayleigh fading channel corrupted by additive white Gaussian noise (AWGN) with N branch selection diversity reception are taken into account. New generalized BER (bit error rate) expressions, which are valid for all values of M, N, E b/N 0 and SIR (signal to interference ration), are obtained and shown to be in excellent agreement with Monte Carlo simulation results. |
