主要通过小波算法，实现对信号的分析，然后通过信号重构，实现与原信号对比。(Wavelet analysis, signal reconstruction)

bee colony optimization for tsp problem

It contains 4 matlab codes for ZF,MMSE,ML equalizer for MIMO systems and 1 document based on linear detector for MIMO system

MIMO信号检测中排序串行干扰消除算法（OSIC）三种排序性能比较，QAM16调制，未编码，AWGN信道(MIMO signal detection interference cancellation algorithm (OSIC) sort sort of three properties, QAM16 modulation, the uncoded AWGN channel)

Matlab的Optimization软件包，虽然能很好地解决线性规划问题，但对于无解和有无穷个解地情况，结果不能让人满意，本人编了几个函数用于打印单纯形表。(Matlab Optimization package, Although able to solve linear programming problems, but no solution and a solution to the endless, the results are not satisfying. I compiled several functions for printing simplex table.)

基于matlab的模拟调制系统仿真 matlab源程序代码(Based the matlab simulation modulation system simulation matlab source code)

Matlab之插值法，包括线性插值，等等(Matlab of the interpolation method, there are close to point interpolation)

关于GPS的MATLAB源程序，经运行验证，算法简单，结果有效。(MATLAB source code on the GPS, verified by running the algorithm is simple, and effective.)

说明：  本文在DCT噪声信号模型研究的基础上,提出了一种新的音频水印嵌入位置选择策略和一个应用该策略的自适应音频水印算法. 通过定义DCT系数的噪声敏感度,建立了水印嵌入位置和嵌入水印后的音频信号的听觉感知性之间的关系,根据音频水印的不可听性的要求选择最优的嵌入位置,然后调节水印强度来满足鲁棒性的要求,从而最大程度地保持音频水 印的不可听性和鲁棒性,为解决音频水印嵌入过程中不可听性和鲁棒性之间的矛盾提供了一种策略.(Though m any w orks in the literature agree that w aterm ark should be em bedded in the middle2fre2 quency coefficients or percep tually significant components, how to determ ine the position em bedded has no universal definition. A new em bedding strategy and an algorithm app lying the strategy are p roposed for audio w aterm arking in DCT dom ain based on research of DCT noise m odal.
