MUSIC-DOA

用matlab语言编写了一个GUI截面，通过该界面可以实现图像的傅立叶变换，反傅里叶变换，高低通滤波，以及把黑白图像转化成灰度图像等功能。(Matlab language with a GUI section, the interface can be achieved through the Fourier transform of the image, anti-Fourier transform, high and low pass filter, and the black and white image into gray image and other functions.)

Rayleigh’s distribution

QAM的matlab编码，可以看QAM的一定信噪比下，信号的误码率情况(The encode of QAM use MATLAB)

BGA布线手册，很好，很强大！搞硬件的朋友可以看看！！！(BGA layout，very good ！)

多元模型回归与分析-2 matlab 程序(multiple regression model analysis with Matlab procedures-2)

说明：  用matlab实现图像角度旋转代码，可以实现图像的任意角度旋转(Angle of image rotation using matlab code, can achieve any angle image rotation)

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.
