手机定位中基于TDOA技术的多种算法的性能比较仿真(TDOA mobile location technology based on performance comparison of a variety of simulation algorithms)

一种改进的LMS算法及其在噪声对消中的应用。在分析传统定步长LMS算法和变步长LMS算法的基础上，提出了一种改进的变步长LMS算法。新算法利用瞬时误差绝对值三次方的指数形式和遗忘因子同时调整步长，更好的解决了收敛速度和稳态误差的矛盾(An improved LMS algorithm and its application in noise cancellation. In the analysis of the traditional fixed step and variable step size LMS algorithm based on LMS algorithm, a modified variable step size LMS algorithm. Absolute value of the new algorithm uses the instantaneous error and the form of cubic exponential forgetting factor while adjusting step, a better solution to the convergence speed and steady-state error of the contradictions)

说明：  matlab中的龙格库塔解算，可以加快程序的运行速度.(matlab in the Runge-Kutta solver, you can speed up the process of running speed.)

表情图像的滤波处理,已经运行过能用，但是使用时，记得改一下路径。(biao qing picture de lv bo chu li,yi jing yu xing guo ,ke yi yong.bu guo ji de yao gai yi xia lu jing.)

本函数是一个通过设置阈值，检测基本通信水印的函数(This function is a through setting threshold value, the function of the basic communication watermark detection)

there is a new approach Using in Wireless sensor network to Clustering, in this approach we use GA algorithm to optimize the lifetime of network.

布朗运动的模拟:模拟了在一个有界平面内，N个点进行布朗运动后的分布情况(brownian motion)

不同的窗函数，都对应不同的幅值修正系数；针对复制修正中最重要的平顶窗，给出修正的方法。(Different window functions, corresponding to the amplitude correction factor copy the most important amendment of the flat-top windows, give a correction method.)

Matlab中龙格-库塔(Runge-Kutta)方法原理及实现(Matlab, Runge- Kutta (Runge-Kutta) method principle and implementation)
