包含了通信系统方面调制解调的基本仿真代码，适合学生学习使用(Communication system includes a basic modem simulation code, suitable for students studying the use of)

里面是几个小波构造的程序，Daubechies小波基的构造，采用多孔trous算法(undecimated wavelet transform)实现小波变换 。(inside several wavelet construction procedures Daubechies wavelet construction, using porous trous algorithm (undecimated wavelet transform) achieve wavelet transform.)

移相键控（PSK）中的二相移相键控（2PSK）算法，建立了MATLAB文件。(Phase shift keying (PSK) in the two-phase phase-shift keying (2PSK) algorithm, the establishment of the MATLAB file.)

现代通信系统matlab版随书代码，很好用的(Modern communication system with matlab edition book code )

通过应用matlab实现高斯算法，用EM估计GMM的数据参数，并把运算时其遗漏数据补全(Matlab achieved through the application of Gauss algorithm estimates GMM data parameters EM, and the missing data when computing its complement)

ofdm调制方式识别的matlab仿真程序，即ofdm信号与单载波信号之间的识别，利用的是高阶累积量作为特征参数(Ofdm modulation mode recognition of matlab simulation program, that is, between ofdm signal with single carrier signal recognition, using the high-order cumulants as characteristic parameters)

这个代码详细的写出了用自然梯度算法进行盲分离的过程，并给出了详细的注释。

SVD水印和提取的水印图像。标志隐藏到宿主图像通过使用密钥

本程序可以显示模拟信号(this program will show an analog signal)

选择重传ARQ协议。自行编写，可以运行，注释详细，结构清晰，易于改写。使用队列实现选择选择重传ARQ，设定了传输时延和最大重传次数。(Select the retransmission ARQ protocol.Written by oneself, can run, annotation in detail, the structure is clear, easy to rewrite.Using queue implementation choices to choose the retransmission ARQ, setting the maximum retransmission times and transmission delay.)
