仿真程序：首先需要用一个随机发生器产生（0.1）内的均匀随机数，然后再将该序列映射到对应的幅度电平｛Am｝。然后将这个范围再分成4个相等的区间，这些子区间分别对应于4个信号比特的符号00，01，10，11。检测器观察到r=Am+n，并且计算r和4种可能传输的信号幅度之间的距离，它的输出Bm就是相应于最小距离的信号电平。Bm与真正的的传输信号幅度比较，差错计数器用来对检测器产生的差错计数。(Simulation program: first need to use a random generator (0.1) the uniform random number, then the sequence is mapped to the corresponding amplitude level {Am}. Then this range has been divided into four equal intervals, these sub-intervals corresponding to four signal bits of the symbol 00,01,10,11. Detector observed r = Am+ n, and calculate r and 4 possible transmission distance between the signal amplitude, its output corresponding to the minimum distance Bm is the signal level. Bm and the real rate of transmission of the signal comparison, error detection counter is used to generate the error count.)

空间调制程序，包含SM，VBLAST,MRc三种算法的性能对比，对空间调制的入门初学者很重要，程序完整，可以直接运行(Spatial modulation procedures, including SM, VBLAST, performance comparison MRc three algorithms for spatial modulation of beginners is very important, program integrity, and can be run directly)

hilditch.m是hilditch细化算法。 RC_unwrap.m是逐行逐列去包裹算法。 least_unwrap.m是最小二乘去包裹算法。 FTP.m是利用傅里叶变换提取相位。 sincosfilter.m是正余弦滤波算法。 以上算法在相位图的相关计算中常用到，比如电子散斑干涉、全息干涉、相移技术等。 (hilditch.m is hilditch refinement algorithm. RC_unwrap.m is listed line by line unwrapping algorithm. least_unwrap.m is the least squares unwrapping algorithm. FTP.m is extracted by Fourier transform phase. sincosfilter.m is the cosine filter. Above algorithm in the calculation of phase diagrams related to the commonly used, such as electronic speckle pattern interferometry, holographic interferometry, phase shift technology.)
