中文摘要:
      近年来Nakagami-m衰落信道仿真模型的研究成为热点。为了得到最佳的衰落信道仿真模型,首先介绍了3种Nakagami-m(m<1)衰落信道仿真方法,分别是基于Beta函数仿真方法、基于近似逆累积分布函数仿真方法以及基于正弦求和仿真方法,通过Matlab仿真软件得到3种方法的幅度、相位以及包络自相关函数仿真图,比较分析得出基于近似逆累积分布函数变换的仿真方法最好,其次是基于Beta函数仿真方法,基于正弦求和方法效果最不理想。
英文摘要:
      With the continuous development of wireless communication technology, the research of Nakagami-m fading channel simulation model has been a hot spot. In order to get the best simulation model of fading channel, three simulation methods of Nakagami-m (m<1) fading channel are introduced, which are based on Beta function simulation method, approximate inverse cumulative distribution function simulation method and sinusoidal summation simulation method. The simulation maps of amplitude, phase and envelope autocorrelation function of the three methods are obtained by Matlab simulation software, and the results are compared and analyzed. The simulation method based on approximate inverse cumulative distribution function transformation is the best, followed by the Beta function simulation method, and the sinusoidal summation method is the most unsatisfactory.
