无线传感器网络LEACH路径国画的matlab程序，有动态效果哦！！！实在难得。(Wireless sensor networks LEACH path painting the matlab program, a dynamic effect! ! ! It is rare.)

matlab编程 包括课件和配套的程序源码 非常适合自学。(matlab programming, including courseware and supporting source code is very suitable for self-learning process.)

rake接收机仿真，参考程序walsh码扩频，三径瑞利信道，三种合并方式(rake receiver simulation, the reference program walsh code spreading, three-path Rayleigh channel, three kinds of merger)

子带编码程序，使用Daubechies（5,3) filter bank，自带降采样及升采样子程序(The subband coding procedures, using Daubechies (5,3) filter bank comes downsampling and upsampling subroutine)

PLS分类，主要用于多数类与少数类的分类。(pls classifier)

设计一CQMFB，低通滤波器H_0 (z)来自一半带滤波器。该半带滤波器的长度为47，通带截止频率ω_p=0.42π，试给出H_0 (z)，H_1 (z)，G_0 (z)，G_1 (z)的幅频响应，单位抽样响应并画图。试着产生一信号，它由两个正弦加白噪声组成，一个在低频，一个在高频，正弦的频率及和白噪声的信噪比自己给定。试用所设计的滤波器组对该信号进行分解和重建。比较重建后的效果，并对结果继续进行分析。(Design a CQMFB, low pass filter H_0 (z) the half-band filter. The length of the half-band filter 47, passband cutoff frequency ω_p = 0.42π, try to give H_0 (z), H_1 (z), G_0 (z), G_1 (z) of the amplitude-frequency response, the unit sample response and Paint. Try to generate a signal that consists of two sinusoidal composition plus white noise, a low frequency, a high frequency in the signal to noise ratio, frequency and sine and white noise of its own given. Trial designed filter group that signal decomposition and reconstruction. Results were rebuilt, and the results continue to be analyzed.)
