高斯过程是一种非参数化的学习方法，它可以很自然的用于regression，也可以用于classification。本程序用高斯过程实现分类！(Gaussian process is a non- parametric method of learning, it is very natural for regression. can also be used for classification. The procedures used to achieve classification Gaussian process!)

matlab 实现c均值算法实现对样本库进行分类，样本库随程序一起上传。(c-means in sorting)

利用matlab生成标准的瑞利分布,方差为1，(generate the rayleigh distribution)

fftshift 比较实数和复数傅里叶变换频谱的不同，以及N取值对其频谱特点的影响。(fftshift more real and complex Fourier transform spectrum of different, and the N values of the characteristics of its spectrum.)

The 802.11 standard specifies a carrier sense multiple access with collision avoidance(CSMA/CA) protocol. In this protocol, when a node receives a packet to be transmitted, it first listens to ensure no other node is transmitting. If the channel is clear, it then transmits the packet. Otherwise, it chooses a random "backoff factor" which determines the amount of time the node must wait until it is allowed to transmit its packet. During periods in which the channel is clear, the transmitting node decrements its backoff counter.
