用MATLAB函数fir1设计一个具有如下指标的线性相位FIR带通滤波器：阻带截止频率为0.55pi 和0.85pi，通带截止频率为0.65pi和 0.75pi，最大通带衰减为0.2dB，最小阻带衰减为42dB。分别利用下面的窗函数来设计滤波器：汉宁窗、汉明窗、布莱克曼窗。对于每种情况，给出其冲激响应系数并画出设计的滤波器的幅频响应。(Designed with a MATLAB function with the following indicators fir1 linear phase FIR band-pass filter: stopband cutoff frequency for the 0.55pi and 0.85pi, passband cutoff frequency of 0.65pi and 0.75pi, maximum passband attenuation is 0.2dB, minimum stopband attenuation of 42dB. Window functions were used to design the following filter: Hanning, Hamming window, Blackman window. For each case, given its impulse response filter coefficients and draw the design magnitude response.)

我用的实现图像分水岭分割的代码！感觉还可以，要用的自己拿去改改(I use the watershed segmentation of image code!)

Systemview是重要的通信系统仿真软件，国外用的很多。这是我做硕士阶段仿真的一些源代码，对通信系统设计开发非常有用，由于没有Systemview这个板块，所以放在这里。这是一个信号平方仿真的Systemview源代码。(Systemview is an important communication system simulation software used in many foreign countries. This is what I do Simulation Master stage some source code, the communication system design and development is very useful. Because no Systemview the plate, so on here. This is a signal of Systemview square simulation source code.)

Rayleigh fading channel based on the Filtered Gaussian Noise method and r based on the Sum of Sinusoids method(simulation for Rayleigh fading channel -Plot the channel output for fm T = 0.01, 0.1 and 0.5 (t/T = 0 ~ 300) – Plot the channel output autocorrelation for fm T = 0.01, 0.1 and 1.0 (fm  = 0 ~ 10))

关于脑电信号预处理中的从脑电信号中滤除心电信号，用的是独立分量分析的方法，编写的程序很简单明了，并画出图形进行直观的观察对比(Pretreatment on EEG signals from the brain to filter the ECG, using independent component analysis method, a program written in very simple and intuitive observation to draw graphics comparison)

This estimator correctly identifies the two distinct directions of arrival.

Just a few functions used in my other toolboxes, for computing MSE and PSNR and some other less common image quality metrics.

对惯性传感器的数据进行处理，结合行人航迹推算方法得到路径(Inertial sensor data processing, combined with the pedestrian trajectory estimation method to get the path)
