hannel estimation performance for Discard Prefix DS-CDMA against the transmitted data vector

说明：  固定提前角法跟踪的数学模型及其仿真程序代码。(A fixed angle in advance of the mathematical model for tracking and simulation code.)

说明：  该程序包里包括了很多跟小波变换有关的经典算法，希望学习小波的朋友可以在其中找到你们需要的代码(The package includes many, many related to the classical wavelet transform algorithm, wavelet friends want to learn can find the code you need)

经典的Extended-Euclid算法，计算GCD。。。(implement Extended-Euclid)

采用神经网络技术模拟地震发生的频率与震级。(using neural network technology simulated earthquake frequency and magnitude.)

基于lms_newton算法的回波消除，直接可以使用(Based lms_newton echo cancellation algorithm, can be used directly)

This function used to calculate PCA of image.

混沌系统分析matlab仿真，适当修改可适用一般系统(Chaotic systems analysis matlab simulation, with appropriate modifications applicable general system)

it helps to enhance the ideas on wimax physical layer.

说明：  人体心电信号的滤波，用一个Butterworth低通滤波器，滤除50Hz工频噪声，并采用不同阶数的Butterworth低通滤波器，比较效果(Human ECG signal filtering, using a Butterworth low-pass filter, filter the 50Hz frequency noise, and different orders of Butterworth low-pass filter, compare results)
