A new Particle Swarm Toolbox (A New Particle Swarm Toolbox )

仿真正弦信号，加白噪声，利用n点平均移动实现对信号平滑处理(Sinusoidal signal simulation, white noise, the use of n-point moving average smoothing to achieve Signal)

说明：  课程中的图像处理实验matlab编程，有助于学习图像处理的初学者(program of matlab image processing , helpful for beginners of image processing)

基于matlab的数字图像处理，实现灰度调整等功能(digital image processing)

学习信号处理的经典代码，使用matlab7以上版本，包含了各种滤波器的源代码(Learn the classic signal processing code, the use of more than matlab7 version contains the source code for a variety of filters)

说明：  跳频是按跳频序列随机改变一个信道所占有频道频率的技术。在GSM 系统中，可利用跳频技术频率分极和干扰分极的特点，改善网络质量。引入跳频技术，可保证在网络软拥塞不上升的情况下，频率复用度较小。(FH frequency hopping sequence is based on a random channel change in the country channel frequency technology. In the GSM system, can make use of frequency hopping technology sub-polar and polar characteristics of interference and improve network quality. The introduction of frequency-hopping technology to ensure that congestion in the network does not increase in the soft case, a smaller frequency reuse moment.)
