EKF codes,很经典的程序，有需要的人可以下载(EKF GPS INS DR)

说明：  draw a signal with its envelope

This is a MATLAB code (function) which implements the Djikstra algorithm.

在三波片式电光晶体结构中利用粒子群优化算法进行模拟的matlab代码(In the three-wave-piece electro-optic crystal structure using particle swarm optimization algorithm simulation matlab code)

这里面有两个程序，两个都是采用4QAM调制。不过个人觉得第一个更容易懂，因为写的很有条理。我改的那个程序就是根据这个来的。 不过在这里面有个问题就是信道系数只能是由高到低，大家可以试试，改成[0.227 0.46 0.688 0.46 0.227]这个是老师给我的仿真中常用的信道系数，这个成为归一化信道，就是系数平方和为1. 第二个程序没有涉及到信道系数，但是这个程序当中，在128个子载波中，前后有32个空载波，这个在OFDM中也是经常用的，这样可以降低误码率。 (And there are two programs, two are based on 4QAM modulation. But personally feel that the first is easier, because the writing is organized. I changed that procedure is based on the past. However, there is a problem in that there is only channel coefficients from high to low, we can try and change into [0.227 0.46 0.688 0.46 0.227] This is the teacher gave me the simulation channel coefficient commonly used, this became normalized channel, is coefficient of the square and is 1. The second program is not related to channel coefficients, but this program which, in the 128 sub-carriers, the before and after the 32 air carriers, the in OFDM is also often used, which can reduce the error rate.)

leach 仿真算法,本人从别人处得到尚未验证,大家共同讨论(leach simulation algorithm, I have not yet been verified from the others at, we discuss)

心电信号的R波检测，特征提取，心率的计算，可视化的检测。简单易懂，使用方便(ECG R-wave detection, feature extraction, heart rate calculation, visualization of testing. Easy to understand, easy to use)

MATLAB扩展编程by 孙永康.ZIP.有需要的朋友请来下载.(MATLAB programming expansion by Sun Yongkang. ZIP. In need of a friend invited to download.)

matlab与excel间的数据交换,主要是关于两者之间数据相互交换的(data exchange between matlab and excel)

这是一个包络线的matlab源程序，包括了仿真程序。不过不是我写的，大家可以参考一下下了(This is an envelope of the matlab source code, including a simulation program. But I did not write, you can refer to a)
