hierarchical-feature-selection

A function that performs mvdr beamforming on every frequency in a source estimation where the doa is known.

q730是模拟低通转换为数字低通.q731是切比雪夫滤波器设计，q732椭圆带通数字滤波器的设计，其中用的是ellipord函数(q730 is converted to analog low-pass digital low-pass. q731 is a Chebyshev filter design, q732 elliptical band-pass digital filter design, which is used in a function ellipord)

freqz对一个采样频率为45.5MHz的信号进行14倍的抽取滤波，同时进行补偿滤波器的设计，并给出CIC滤波器、补偿滤波器和级联后的频谱图 ( for the droop in the passband for the CIC decimator.Design a minimum-order CIC compensator that compensates... . )

说明：  Matlab在数字信号处理的应用,xju的教学ppt,很不错.(Matlab in digital signal processing applications, xju teaching ppt, very good.)

In this paper, we propose and investigate a lowcomplexity human motion tracking system which is based on ultra-wideband (UWB) radio nodes.

very important to understand tomography of medical MRI images

I forgot the name of codes

SO BP神经网络的实现，有神经网络源程序，带附录说明(SO BP neural network to achieve, there are neural network source, with appendix explains)

说明：  实验一 模糊聚类的图像分割 MATLAB(MATLAB )

极大似然算法辨识程序, 系统辨识里面常用的辨识方法(Maximum likelihood algorithm for identification procedures, system identification methods which identification of common)
