nmap最新windows环境下的源代码，对提高大家的编程能力有很大帮助(The latest source nmap windows environment, to improve our programming skills are very helpful)

多径传播的部分代码，包括傅里叶变换，傅里叶反变换，幅频和相频特性(Multipath propagation part of the code, including Fourier transform)

使用matlab仿真随机编码过程，可以成功运行(To use matlab simulation of random coding process can be run successfully)

基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)
