CDMA系统在加性高斯白噪声、瑞利多径衰落、赖斯衰落信道里的性能(CDMA system s performance in AWGN and Rayleigh and Rician Channel)

说明：  此程序用语计算信号的位移是用MATLAB编写的,是一函数的形式可以直接调用 (Term this procedure the calculation of the displacement signal is prepared MATLAB is a function of the form can be directly called)

EMD是处理非线性、非平稳性信号的有效的新方法，本程序是振动信号EMD分解程序，可以把振动信号分解成多个IMF分量和一个残余量。(EMD is nonlinear, effective new method of non-stationary signals, this program is the vibration signal EMD decomposition process, the vibration signal can be decomposed into multiple components and a residual amount of IMF.)

说明：  数据预测之BP神经网络具体应用以及matlab代码(Application of BP neural network in data prediction and matlab code)

这个程序是我做“化工过程综合与优化”课程设计时编写的。主要用于换热器设计的计算，含有注释。 (This code can be used to design the heat exchanger.)

Comparison of performance for 2-PPM and 2-PAM under two pulse shapes, Gaussian Pulse and Hermit Pulse with Three scenarios are considered (5, 20, and50 users).

principal component analysis

Image enhancement in frequency domain using Fourier center frequency, Gaussian lowpass filter, Low pass filter, high pass filter. Image restoration using medean filter, weiner filter with noise generator such as Gaussian noise, Salt and Pepper noise

基于matlab编写的小程序，可以实现观察信号的泄漏现象，亲自验证好使。(Based on matlab prepared applet, you can achieve the observed signal leakage phenomenon, personally verify so.)
