单径或多径瑞利衰落信道仿真，使用高阶累积量对MPSK信号进行调制识别，考虑雨衰 阴影 和多径影响。( Single path or multipath Rayleigh fading channel simulation, Using high-order cumulants of MPSK signal modulation recognition, Consider shadow rain attenuation and multipath effect.)

说明：  基于矩阵特征值分解的功率谱估计包括特征向量估计和MUSIC估计，这两种估计方法均为非参数估计方法(Based on Eigenvalue Decomposition of power spectral estimation, including estimation and MUSIC eigenvector estimates, these two estimation methods are non-parameter estimation)

说明：  QR分解是球形MIMO检测算法必不可少的环节,本代码采用m语言描述了QR分解分解具体怎么实现,而不是直接调用matlab内部函数,采用的是QR分解的脉动阵列结构,据此代码可轻易实现QR分解的FPGA设计(QR decomposition is an essential part of the spherical MIMO detection algorithm, the code uses QR decomposition decomposition m language to describe specifically how to achieve, rather than a direct call matlab internal function, using the QR decomposition systolic array structure, pursuant to which the code can be easily QR decomposition FPGA design)
