说明：  假设移动用户从距离基站1英里的地方开始以每小时40英里的恒定速度相基站移动，仿真移动用户在这2s时间间隔内所接收的信号（及其频谱）(Suppose mobile user from the base station a mile from the start where the constant speed of 40 miles per hour relative to the base station mobile, mobile users in the 2s simulation time interval the received signal (its spectrum))

hey there!this is the matlab code for DEC protocol for wireless sensor networks.hope you will find it helpful...

这是模式分类一书中第五章的固定增量感知器和带裕量的变增量感知器的matlab代码实现。(This is the pattern classification of a book chapter V and the fixed-increment perceptron with margin perceptron incremental change of the matlab code.)

matlab实现的对黑白图像上色的功能，提供可以直接运行的m文件以及大量图像素材。(for black and white images to color functions matlab to achieve, provided m files can be run directly as well as a large number of image material.)

1、系统仅处于训练状态。训练序列为2cos(2π×f1×n/fs)， 干扰为sin(2π×f2×n/fs)；序列长度为100个样点。 其中n=0…99，f1=1kHz，f2=2kHz，fs=8kHz。 2、采用LMS算法，均衡器输入为训练序列加上干扰，均衡器阶数为21阶，步长因子β=0.01。 3、在Matlab中编写浮点LMS算法，绘制均衡器的输出波形，并与训练序列进行对比。 (1, the system only in the training status. The training sequence is 2cos (2πf1n/fs), interference sin (2πf2n/fs) sequence length of 100 samples. Where n = 0 ... 99, f1 = 1kHz, f2 = 2kHz, fs = 8kHz. 2, using LMS algorithm, the input to the equalizer training sequence plus interference equalizer order is 21 bands, step factor β = 0.01. 3, the preparation of the floating-point LMS algorithm in Matlab, draw the output waveform equalizer, and with the training sequence comparison.)

说明：  MATLAB编程教程，对初学者非常有用。 请大家多用用MATLAB编程(MATLAB programming tutorial, very useful for beginners. Please keep on with the use of MATLAB programming)
