QPSK

经过测试，发现这个代码结果很好，而且可以 和别的程序结合，恩不错的(tested and found very good results this code, but can and other procedures, TU good)

卷积码vitebi译码的matlab程序(Decoding convolutional codes vitebi matlab program )

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

特征提取实例中的确定圆形目标源程序，能有效提取出图像中的圆形目标，并标记(Feature extraction instance to determine circular target source, can effectively extract the image of circular target, and mark)

说明：  gpr algoritm from FTFD perspertive

收集的有用的工具箱bat文件可以编辑，也可以将其修改成自己的东西。。。(Collection of useful toolbox bat file can be edited)

单脉冲和差波束测角程序。 此程序实现了线阵8阵元的和差波束测角，利用全阵同时形成两个波束，形成和差波束，随着测量角度的增大其误差也逐渐增大，这是由于这种方法的近似所致和波束扫描时变胖(Single-pulse and beam deviation angle measuring procedures. This program implements linear 8-element array and differential beam angle measurement, using the whole array at the same time to form two beams, beam forming and poor, with the measurement of the angle increases the error also increases, which is a result of this approach approximate due to fat, and beam scan)

最新的一篇关于研究视网膜眼底图像配准的文章，很有参考意义(Latest article on the study retinal fundus image registration articles, great reference significance)

通过求解Chirstoff方程，求解出材料的群速度和慢度面(compute the sowless and group velocity)

适用于matlab平台，用来模拟晶粒长大的源程序。(For matlab simulation of grain growth source program)
