此程序为matlab函数，实现用结构相似性（SSIM）准则评价图像，与峰值性噪比的作用类似。(This program is a matlab function, and criteria for evaluation of structural similarity (SSIM) image acts like a peak-noise ratio.)

Applied Numerical Methods Using MATLAB -

说明：  用matlab程序编写，计算分形图像的计盒维数。(Programming using matlab to calculate the fractal box dimension image.)

说明：  有关矢量信号处理的基本仿真，得到声压功率谱，x,y.z各方向声强谱(Vector signal processing related to the basic simulation，underwater acoustic)

It s a matlab code for rls (recursive least squares) algorithm.

First use EEMD to decompose the original singal to get IMFS,then use FFT to analyse the each IMF,combine EEMD with FFT to get clearer analytic results.

毕业设计的基于8QAM+zcz序列的准同步CDMA通信系统仿真(　　　This article will be given below 8QAM+ ZCZ sequence sets up method and analysis, will further introduce the relevant definitions zero correlation sequence and some properties and characteristics, including non-cycle related, cycle-related, Qi cycle and other characteristics. The reason why is because the study of these theories using this sequence, in the Gaussian channel conditions and system performance in terms of interference is very similar to the synchronization system and the system performance is far superior to an asynchronous system, and the extended sequence comparison the original sequence has better performance.)
