Model

说明：  用C语言编的wimax 信道模型，绝对原创！(Wimax compiled by C language channel model, the absolute original!)

I have thoroughly study the basic of image compression techniques. From that I have selected SPIHT algorithm for my research work. I have implemented on image compression for gray images using SPIHT algorithm. Image compression is implemented using this algorithm has better result over the previous result on gray images and also improved PSNR value high but on other side low result on compression ratio.

该程序源代码实现了CDMA通信系统性能的仿真，用MATLAB实现了直序、跳时、跳频以及M序列，GOLD序列等的产生，及在AWGN和RAYLEIGH环境下误码率的计算(The program source code to achieve the performance of CDMA communication system simulation, using MATLAB realize the direct sequence, time hopping, frequency hopping and M sequences, GOLD sequence generation, and in the AWGN environment and RAYLEIGH BER calculation)

此为雷达对抗的基本知识.对初始学习的人有一定的帮助.(This is the basic knowledge of radar confrontation. For the initial study were certainly helpful to them.)

MATLAB低通滤波程序，很好的源代码，希望对大家家有用-filter ， (MATLAB low pass filtering process, a good source code, I hope useful for all of us home-filter)
