OFDM系统，子载波数目1024，前缀数目256，循环数目256，加入了高斯白噪声(OFDM system, the number of subcarriers 1024, the number prefix 256, the cycle number of 256, by adding a Gaussian white noise)

用matlab对信号进行功率谱估计的几种方法(The signal using matlab several methods of power spectrum estimation)

matlab 傅里叶展开 波形分解 振动分析(matlab Fourier decomposition on waveform Vibration analysis)

中频通信信号信噪比的快速盲估计 中频通信信号信噪比的快速盲估计 (Fast Blind SNR Estimation of IF Communication Signals )

本程序的目的是模拟一个ARMA模型，然后进行时频归并。考察归并前后模型的变化。(The purpose of this program is to simulate a ARMA model and then to merge time and frequency. The changes of the model before and after the merging were investigated.)

说明：  该程序可以实现对于信号的时域参数提取以及信号的包络分析(The program can realize time domain parameter extraction of signals and envelope analysis of signals)

说明：  MATLAB程序（附图像），利用灰度AGV对路径进行识别。(MATLAB (AP like), using gray AGV right path for identification.)
