中文说明：最终的权值矩阵就是滤波器的系数，应用小区域方差对比，程序简单，FMCW调频连续波雷达的测距测角，对于初学者具有参考意义，IMC-PID是利用内模控制原理来对PID参数进行计算，搭建OFDM通信系统的框架。
English Description：
Final weight matrix is that of the filter coefficients, the application of small regional variance contrast, the program is simple, the FMCW frequency modulated continuous wave radar ranging and angle measurement, for beginners has reference significance to IMC-PID is by using the internal model control principle of PID parameters are calculated, and build a framework for OFDM communication system.
