(7,3) rs code bit error probability simulation

LDPC编码译码的Matlab代码，主要考察吞吐量随信噪比变化的关系。demo文件运行程序，其他文件为自己编的函数。(The LDPC codec Matlab code, mainly on the throughput changes with the signal-to-noise ratio. demo file to run the program, and other documents made themselves function.)

MIMO通信系统的仿真源代码，是书籍中的源代码，可以跑(MIMO communication system simulation source code)

This is a detector of RR based on wavelet for ECG os 1khz sample frequency

Simulation Distribution 3

计算图像峰值信噪比psnr的matlab源程序,相对路径转绝对路径的matlab程序(computing image PSNR psnr the Matlab source, relative to the absolute path of Matlab procedures)

此程序为基于GM（11）的灰预测程序，进行数据预测，最少输入数据为两个(This procedure the gray prediction program based on GM (11), data predicted minimum input data into two)

pv cell modeling SIMULINK PV CIRCUIT MODEL

sobel算子，边缘检测算法，对初学者有参考作用(sobel operator, the edge detection algorithm, a useful reference for beginners)

本程序先使用RSSI中对数常态模型来测距离，然后用三边测量法来计算未知节点的坐标。(The program first uses RSSI in lognormal model to measure the distance, and then use trilateration to calculate the coordinates of the unknown node.)
