MATLAB30

A simple PSNR calculator that might be handy in measuring the PSNR between two frames in a video. Typically used in measuring the distortion when videos are encoded and decoded.

很有用的一些代码　对于新手很有用的　可以下来(Some useful code for the novice can be very useful down)

PID仿真程序，且带有扰动信号，仿真结果理想，PID的抗扰动能力好(PID simulation program, and with the disturbance signal, the ideal simulation, PID good anti-disturbance)

Stretches contrast on the image and normalize image from 0 to 1. The main difference of this function to the standard stretching functions is that standard function finds global minimum and maximum on the image, then uses some low and high threshold values to normalize image (values below LowTHR are equated to LowTHR and values above HighTHR are equated to HighTHR)

频率同步算法的时域方法。利用两个连续重复的符号计算频率误差估算。(Frequency synchronization algorithm for time-domain method. The use of two consecutive duplication of symbolic computation to estimate frequency error.)

It is Radar System design and signal prcessing code based on standard algorithm .this is vey important for biggener those who are working on Radar signal processing area.This code contain various chapter. this is basically chapter No8

这是对OFDM系统的一个仿真程序，平台是 MATLAB，对这样一个正交频分复用系统的理解很有好处。(This is an OFDM system, a simulation program, the platform is MATLAB, to such a orthogonal frequency division multiplexing system is very good.)
