有信道编码，调制，信道估计等，信号维数的估计，采用了小波去噪的思想，IMC-PID是利用内模控制原理来对PID参数进行计算，抑制载波型差分相位调制，matlab程序运行时导入数据文件作为输入参数，快速扩展随机生成树算法，从先验概率中采样，计算权重。- Channel coding, modulation, channel estimation, Signal dimension estimates, Using wavelet denoising thought, The IMC- PID is using the internal model control principle for PID parameters is calculated, Suppressed carrier type differential phase modulation, Import data files as input parameters matlab program is running, Rapid expansion of random spanning tree algorithm, Sampling　a priori probability, calculate the weight.
