计算两个等长信号的相关曲线 ，并绘出图形。采用取地址操作 运算速度快(Two other long signal calculated correlation curve, and draw the graph. Address by taking action fast speed)

关于turbo码网格计算的仿真程序，对网格图的简化计算提出了新的实现(Turbo codes on the grid computing simulation program, to simplify the calculation of the grid map proposed a new realization of)

说明：  dpsk信号的调制与解调 是基于matlab开发环境

A计权滤波器,用于声音信号的A计权滤波，需要声压信号和采样频率，即可得到滤波后的时程信号(A weighting filter, A weighting filter for voice signal, need sound pressure signal and the sampling frequency, you can get the schedule of the signal after filtering)

ldpc码的matlab仿真程序，希望对大家有用，不客气，(LDPC codes matlab simulation program, in the hope that useful, at worst,)

说明：  sigma点卡尔曼滤波在跟踪中的应用，能够实现较好的跟踪效果(sigma point Kalman filter in tracking application, can achieve better tracking)

说明：  Matlab下生成最短路径的程序。首先在m脚本文件canshuo.m中输入节点个数和路径权重，在命令窗口中输入canshu，用s=12,e=10的格式输入要求的起止点，再输入main即可得到两点之间的路径和长度。(This is the codes for Matlab to generate the shortest way.)

阿基米德曲线的绘制，GUI显示，有推导公式，可自行修改参数。(Archimedes spiral，you can change the parameter by your need)
