有较好的参考价值，搭建OFDM通信系统的框架，IMC-PID是利用内模控制原理来对PID参数进行计算，微分方程组数值解方法，针对EMD方法的不足,脉冲响应的相关分析算法并检验，分析了该信号的时域、频域、倒谱，循环谱等,包括调制，解调，信噪比计算。- There are good reference value, Build a fr a mework OFDM communication system, The IMC- PID is using the internal model control principle for PID parameters is calculated, Numerical solution of differential equations method, For lack of EMD, Related impulse response analysis algorithm and inspection, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Includes the modulation, demodulation, signal to noise ratio calculation.
