这是一个低通抽样定理，例题中包括了低通信号的波形，抽样速率为4Hz的抽样信号，抽样序列恢复出原始信号(This is a low-pass sampling theorem, examples included in the lowpass signal waveform, the sampling rate is 4Hz sampling signal to recover the original signal sample sequence)

这是我找到的MATLAB神经网络程序设计源程序(This is what I found MATLAB neural network program design source)

psk调制，给出了不同抽样速率和信噪比下的仿真结果(psk modulation, given the different sampling rate and SNR of the simulation results)

在共梯度法中 只有当初值的选取靠近最优解时 迭代才会收敛 当远离时发散 且 当精度控制为0.1时可以实现 但设为0.01时就实现不了(numeberica method)

本源码是基于多尺度的retinex理论的实现代码，针对灰度和彩色图像均可使用！！ (The source is based on the theory of multi-scale retinex implementation code for gray and color images can be used! !)

OFDM的MATLAB经典程序，可以实现有关OFDM的主要仿真，已经验证(OFDM classic procedures of MATLAB, you can achieve the main simulation of the OFDM, has been to verify)

说明：  如题，层次分析法的matlab程序 方便实用，尤其是针对不太熟悉matlab程序设计的人(err)

基于泊松过程的检测与估计原理和方法，对无符号间干扰信道中的类似问题进行仿真，并最终给出了仿真数据趋势图。(Poisson process based on principles and methods of detection and estimation of inter-symbol interference-free channel to simulate a similar problem, and ultimately gives the simulation data trends.)

采用PN码作为扩频码对信号进行扩频处理，采用BPSK进行调制，在加高斯白噪声的信道中进行传输，解调，误码率等(Using PN codes as spread spectrum code to spread spectrum signal processing, using BPSK modulation, in add white gaussian noise channel transmission, demodulation, bit error rate, etc)

Matlab产生ECG波形的程序，值得一看。(Use Matlab to generate ECG wave )
