基因遗传算法中的一元函数的优化举例，供广大初学之人黏贴使用(Genetic algorithm optimization of unary function example, for the majority of beginners person adhesive used)

利用matlab在图像中加入各种随机噪声，包括调用函数，以及randn使用、以及介绍send和state的区别。(Using matlab to join all kinds of random noise in the image, including the calling function, and randn use, as well as the introduction of the difference between send and state.)

三个分段相连的信号的傅里叶变换和时频分析；Chirp 信号的傅里叶变换和时频分析；信号的子带分解(Linked to three sub-signals Fourier transform and time-frequency analysis Chirp signal Fourier transform and time-frequency analysis signal subband decomposition)

说明：  一个ask调制解调的源程序，可以自己添加一些噪声进行仿真分析！(Ask modulation and demodulation of a source, you can add some noise to conduct their own simulation analysis!)

psk调制与解调的m文件仿真，希望对大家有所帮助。(psk modulation and demodulation of the m file simulation, we want to help.)
