G729-decoder

该程序实现改进的自适应相关算法，两个matlab文件，一个为函数，该函数求出信号特征量的马氏距离平方并通过梯度下降法训练出其固定阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号特征量的马氏距离平方及其固定阈值求出来，并一起画出图来。 (The program features improved adaptive correlation algorithm, two matlab files, one for the function that calculate the square of the Mahalanobis distance of signal characteristics by gradient descent to train the fixed threshold, the other main function, call The function files the program seek out the square of the Mahalanobis distance and fixed threshold of each channel signal, there are four chanel signal,then draw them out together)

lms算法的实现 计算了剩余均方误差和失调参数(MVDR based on singular value decomposition method of frequency estimation of the simulation)

matlab实现特征值的计算，对于初学者非常有用。从书上下载的源代码。(Feature is matlab calculation, is very useful for beginners. Downloaded from the book source code.)

贝叶斯分类器实现多类识别，主要用于两类的识别(BAYES_CLASSIFIER function calculates the discriminant functions for two classes. )

比较了不同降秩的LMMSE算法的不同用于OFDM系统仿真(Comparison of different reduced-rank LMMSE algorithm for OFDM system simulation of different)

The source code used here is useful for evaluating the degree of the bspline

matlab的调制解调， matlab的调制解调(matlab modem, matlab modem)

相关函数法该方法先由序列估计出自相关函数R，然后对其进行傅立叶变换，得到功率谱估计。当延时和数据长度相比很小的时候可以有良好的估计精度。 (Correlation function method that the method is estimated by the sequence from a correlation function R, then its Fourier transform, the power spectrum estimation. When the length of delay and data can be compared to a very early age have a good estimation accuracy.)
