信号处理中的若干典型算法，很不错的，希望对大家游泳(signal processing algorithms typical of a number of very good, we hope to swim)

算术编码实例，matlab编写的简单编码过程(encode symbol)

读取segy数据、文件，写道头卷头等等，内置说明书，简单易用(Read the segy data, file, writes head roll and so on, the built-in instructions, easy to use)

说明：  AES加密算法中的S-盒及其MATLAB实现,S盒实现是MATLAB中的主要过程。(AES encryption algorithm in the realization of S-boxes and MATLAB, S box MATLAB implementation is the main process.)

simulation of communication systems and software defined radio matlab codes from the book

说明：  用牛顿下山法求解方程：下山因子在计算过程中可以变动，一般选择下山因子时从1开始，逐次将减半进行试算，直到能使下降条件成立为止。若当计算到某步时取不到满足要求的值（或值小到无法容忍），这时称“下山失败”，需要另取初值重新算起。(Descent method with Newton' s equation: down factor in the calculation process can change, usually selected from the 1 start down factor, will be halved for successive spreadsheet until the can down the conditions established. If when calculating the time to take a step not meet the requirements of the value (or values ??too small to tolerate), then the &quot down failed&quot , you need an alternative initial re-counting.)

matlab 数字基带传输系统 全真模拟(Matlab digital base-band transmission system simulation of the whole truth)

正交相移键控 (Quadrature Phase Shift Keying)简称“QPSK”，是一种数字调制方式。它分为绝对相移和相对相移两种。由于绝对相移方式存在相位模糊问题，所以在实际中主要采用相对移相方式DQPSK。目前已经广泛应用于无线通信中，成为现代通信中一种十分重要的调制解调方式。(QPSK THAT IS TO SAY....)

利用PSO算法求解分布式电源的选址定容问题，并考虑了分布式电源的随机性(Randomness of the PSO algorithm DG locating and sizing issues and considered the DG)

同步压缩变换时频分析，大家可以试一试试试(Synchronous compression transform time-frequency analysis, we can try it)
