好多计算程序，可用于分析和计算！如：小波分析、时间序列等！(calculating program, eg:wavelet analysis)

说明：  一种用MATLAB实现的改进的模式退火算法的编程，模拟退火是智能计算中很重要的算法之一。(Using MATLAB to achieve a kind of model annealing algorithm to improve the programming, simulated annealing is a very important intelligent algorithm calculation one.)

梳状导频方式下OFDM系统的LS、LMMSE算法比较(Comb Pilot OFDM system under LS, LMMSE algorithm)

说明：  计算图像的偏移量，用于图像间没有旋转的图像配准(Offset images are calculated for the image registration)

帝国算法：初始化，帝国同化，帝国更新，帝国竞争，帝国删除。与粒子群算法比较(ICA social politic)

OFDM链路级的仿真器场景是单小区单用户，信号从发送端发送，在接收端进行信号估计。估计误差可以从接收和发送信号的不同得到。仿真器的输出是BLER/BER vs SNR。(OFDM Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table。)

MATLAB常用函数参考,各种函数命令，操作指南。(MATLAB function reference, a variety of command functions, operation guide.)

说明：  用Matlab与C的混合编程写的FFT（快速傅立叶变换）算法，具有运算快，易于使用和理解的优点。(Using Matlab and C programming to write a mixture of the FFT (Fast Fourier Transform) algorithm, with the operator fast, easy to use and understand the advantages.)

旋转子空间程序，实现DOA定位，可用于DOA的学习使用(Subspace rotation procedures to achieve DOA positioning, can be used to study the use of DOA)

说明：  自动发送邮件，使用该程序可以实现邮件自动发送(Send mail automatically)
