N=11，41，81，121时，用矩形窗设计一个低通FIR滤波器，其剪切频率wc＝0.3л(N = 11,41,81,121, the rectangular window design with a low-pass FIR filter, its cut frequencies wc = 0.3л)

直方图均衡化 直方图的均衡化可以使图像的像素灰度值动态范围变大，增强图像的对比度看起来更清晰。上图经过直方图均衡化方法处理后不再特别暗淡，其直方图反映出来的灰度的概率分布也相对比较均匀(Histogram equalization)

多址接入协议仿真,内含aloha、npcsma、saloha及三个测试ex1、ex2、ex3，对多址接入协议仿真与建模非常有帮忙哦，欢迎下载。(Containing multiple access protocol simulation, aloha, npcsma, saloha and three test ex1, ex2, ex3, simulation and modeling for multiple access protocol is a lot of help oh, welcome to download.)

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.)
