说明：  跳频扩谱通信matlab代码，实现跳频通信系统仿真。(Matlab code for frequency hopping spread spectrum communications, to achieve frequency hopping communication system simulation.)

tutorial on fuzzy logic

利用matlab构建toeplitz循环矩阵(toeplitz in matlab)

说明：  不错的matlab通信工具箱使用，强力推荐(Good matlab communication toolbox to use, highly recommended)

matlab 遗传算法工具箱，就这么简单非要20字(matlab genetic algorithm toolbox, so simple insisted 20th)

按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(According to a given target analog low-pass filter (Butterworth or Chebyshev low-pass low-pass) to approximate the ideal analog low-pass filter, then through the bilinear transformation method to digitize the analog filters, digital filters has been .)

说明：  实现基频提取的RAPT算法（一种鲁棒性的基频提取算法）。输入文件为wav波形文件。(A Robust Algorithm for Pitch Tracking (RAPT))

说明：  批量读取csv文件 并保存成mat格式 有助于做大量数据处理的人(Read csv file and save into mat format)

说明：  在扩频系统中再如不同得衰落的情况进行仿真(in spread spectrum systems in different Another example of the decline of Simulation)

This code shows in a simple way the implementation of 2 dimention finite difference time domain simulation. We also implement perfectly match layer at the border.
