说明：  MATLAB code for simple edge detection algorithms including simple mask, sobel mask, Gaussian derivatives.

64-QAM通信系统设计 有代码 有doc文件(64-QAM communication system has a doc file code)

buck变换器仿真，直接可用，修改参数即可(buck converter simulation, directly available, you can modify the parameters)

turbo乘积码，子码扩展汉明码，译码用chase算法(turbo product code, subcode extended Hamming code decoding algorithm with chase)

It is a very useful matlab program to plot a 3D graph by using sfunction and it shows how to use multiplexur for x, y and z signals. Enjoy it and good luck.

LDA algorithm for matlab

说明窗函数为文献窄时，STFT无频域的定位功能；(Note, when a narrow window function of literature, STFT-free frequency domain positioning function )

说明：  用matlab实现的fp树。目的是发现频繁项集，但是本代码只是实现了fp树(Fp tree with a matlab implementation. Aim is to discover frequent itemsets, but only realized the fp tree code)

说明：  数字信号处理设计与仿真分析 (1)建立两个模拟信号的数学模型 sa1(t)和 sa2(t)， 其中 sa1(t)是有用信号， sa2(t)是干 扰信号。 两个信号的中心频率、信号带宽等参数由学生自己选定，要求两个信号的频谱不重 叠， sa2(t)的幅度比 sa1(t)的幅度高 20dB， 两个信号时域叠加得到合成信号 xa(t)， 即 xa(t)= sa1(t)+ sa2(t) 设计计算机程序仿真产生 sa1(t)、 sa2(t)、 xa(t)信号， 分别画出三个模拟信号的时域波 形和频谱图；(Establish two mathematical models of analog signals sa1(t) and SA2 (t), where SA1 (t) is the useful signal and SA2 (t) is the dry signal Interference signals.)
