本代码可以根据给定的小区数目和小区半径生成网络拓扑结构，并返回基站位置坐标(This code can be based on the given cell number and cell radius generated network topology, and return to the base station coordinates)

正弦脉宽调制， 程序给定调制波频率，载波频率，负载功率因数，输出相电压波形，相电流波形。(Sine pwm,the frequecy of modulated wave and carried wave is given in program, also the factor of load.The output is wave of phase voltage and phase current.)

根据Clarke模型对无线信道进行建模，建立了瑞利信道模型(According to Clarke for modeling wireless channel model, the establishment of Rayleigh channel model)

可以实现MIMO系统在锐利满衰落和高四百噪声信道下的几种天线结构的容量。(MIMO system can be achieved over a sharp decline and high noise channel 400 under the capacity of several antenna structure.)

this program is maily for slm , but u can input the unmber of ofdm or the length of n for BPSK

tracking1 is used to track a man in video

基本电路，用于实现低通滤波器，可以仿真波形。(failed to translate)

calculates the signal to noise ratio in each subchannel

PCH coding 编码仿真 ， matlab 实现(PCH code simulation, matlab implementation)

The aim of this application is to implement scalable mpeg type compression by varying DCT coefficients and finding minimum number of DCT coefficients that can give minimum acceptable quality.. This application only works for gray scale.
