固定收益经典文献，详细论述各类固定收益产品设计与开发，不可多得的学习材料。(Fixed Income classic literature, discussed in detail the design and development of various types of fixed-income products, a rare learning materials.)

BPSK,QPSK等多个调制方式的详细说明及matlab代码(BPSK, QPSK modulation and other detailed instructions and matlab code)

完整的mat格式的USPS手写字府库，里面包括7291个训练样本和2007个测试样本(USPS handwritten database of mat format,include 7291 cases for training and 2007 cases for testing.)

白噪声和有色噪声的生成方法，参数可以由用户自己设定(White noise and colored noise generation method, the parameters can be set by the user)

this is simmulation QPSK modulation in rayleigh channel

本程序主要是把相同的类聚在一起，便于后续的分类，方法使用简单方便。(This procedure is the same class together, to facilitate the subsequent classification method easy to use.)

Compensadores en adelanto y atraso

实现CDMA的matlab程序，程序很完整，需要的自己来看啦(CDMA-matlab program to achieve the program is very complete look at the needs of their own啦)

采用鱼群MP算法来对单信源AFSA波达方向估计，可以得到很好的结果(Adopt shoals MP algorithm to single source AFSA doa estimates, you can get a good result )

这个函数也要被melcepst函数调用，用来进行计算Mel倒谱系数。这个函数的作用是构造mel滤波器组。(This function must be called melcepst function is used to calculate Mel cepstral coefficients. The role of this function is to construct mel filter bank.)
