OFDM_simulation_using_matlab

Stuff. This is only to become a uploading member to start working on a Chinese language system for my programs. I will upload soon.

改进之前做过的倒立摆控制程序，使用PID控制并分析其性能(Improvements done before the inverted pendulum control procedures, the use of control and analysis of its performance PID)

Matlab code for extraction

大地测量学原理坐标转换程序，能实现大地坐标到平面的互相转换(The geodetic coordinate conversion program principle, can realize the earth coordinate to plane conversion to each other )

这三个小程序都是matlab的.m文件，分别实现用灰度变换的方法增强图像的对比度和直方图均匀化，模拟图像受高斯白噪声和椒盐噪声的影响。(The three procedures are Matlab. M documents, were used to achieve gray transform method to enhance the contrast of the image and histogram equalization. Simulation images by white Gaussian noise and the noise of Salt and Pepper.)

基于四向最小二乘解包裹算法，可以实现对包裹相位的相位展开(forth DCT phase unwrapping alogrithm)

OFDM系统，有（2，1，7）卷积码编码，分组交织，viterbi译码(OFDM system, there are (2,1,7) convolutional code encoding, packet intertwined, viterbi decoding)

it is ocksvm with matlab

无速度传感器matlab仿真模型，带测试模型(No speed sensor matlab simulation model with test model)

IEM模型，积分方程模型，模拟地表HH计划下后向散射系数(IEM model, integral equation model, simulated surface HH program backscattering coefficient)
