通信系统的防真，用matlab编写，ＱＰＳＫ(communication system simulation by matlab,ＱＰＳＫ)

说明：  傅里叶函数的表现形式，这个在matlab里面非常的常见，可以作为参考(Fourier form of the function, this is very common in matlab which can be used as reference)

说明：  用模拟退火算法解决tsp问题，适合初学者(With the simulated annealing algorithm to solve the problem tsp )

说明：  本代码是由matlab实现蔡氏电路的混沌仿真，采用的是四阶龙格-库塔方法，比较简便。(This code is a matlab implementation of the chaotic Chua' s circuit simulation, using a fourth order Runge- Kutta method, more simple.)

This is a test code to show the spectrum of sine wave.
