本压缩包是里面是用matlab编写的QPSK信号调制与解调的程序，程序十分简练。(The compressed package is written in matlab which is QPSK signal modulation and demodulation process, the program is very concise.)

MATLAB7.0基础教程_清华大学，很好的教材，适用于0基础的人(Tutorial for MATLAB7.0)

说明：  程序实现了瑞利衰落信道的matlab仿真！给出了matlab源码程序！(The program perform the simulation of RayleighFading in matlab!the code in matlab is avalible!)

（7，4）系统循环码译码器 decode_out = cyclic_decoder(decode_in) 该系统循环码译码器的生成多项式是g(x) = x^3 + x + 1 输入参数decode_in是接收到的循环码字，是1×7的行向量；输出decode_out是解 码后的信息码字，是1×4的行向量。 函数运行时，同时画出接收循环码字和译出码字的波形图。 ( (7,4) system cycle Decoder decode_out = cyclic_decoder (decode_in) cyclic code decoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 input parameters decode_in is the received codeword cycle, the row is 1 × 7 vector output decode_out solution code is the information after the code word is 1 × 4 row vector. Function to run at the same time code word and draw a circle to receive the word of the translated code waveform.)

基于傅立叶变换的ofdm模型信道是高斯信道(OFDM model based on fft transform)

matlab仿真最大似然估计法，简单易懂，适于初学者使用。(matlab simulation of the maximum likelihood estimation method, easy to understand, suitable for beginners to use.)

该程序是同步中的相位估计方法，该方法可以估计不同参数下的相位大小。(synchronization is the process of phase estimation method, which can be estimated under different parameters of phase size.)

图形图象中dct变换中用到的反zigzag扫描原代码是基于matlab中的开发(graphic images used Copy transform the anti-Zigzag scanning source code, which is based on Matlab Development)

此程序是计算wigner-ville分布、伪wigner-ville分布和平滑伪wigner-ville分布的程序，需要下载matlab时频分析工具箱(This procedure is the calculation wigner-ville distribution, pseudo-wigner-ville distribution and smooth pseudo-wigner-ville distribution procedures need to download the time-frequency analysis matlab toolbox)
