该算法程序调用格式为[y,w]=bksa(x),其中x是一个n*T的数据矩阵，y是估计出的源信号矩阵，w是n*n分离矩阵。">

文件用于数字通信信号的调制方式识别，包含调制信号的产生，模拟通信信道，以及特征量的计算（共5个特征量，分两个程序计算），最后是信号调制方式的识别。(Files for digital modulation recognition of communication signals, including modulation signal generation, Simulation communication channel, and the calculation of features(a total of five features, calculated in two programs), and finally the signal modulation recognition.)

Artificial Intellegence: backpropagation

Integers is given a rectangular matrix. define: 1) The number of rows containing at least one zero element 2) the number of the column in which the longest series of the same elements

自己编写的短时傅里叶变换（STFT）程序，短时傅里叶变换可以获得非平稳信号的时频图，主要原理是用滑窗截取一段信号，认为这一段时间内信号是平稳的，对其进行fft变换获得频谱(I have written a short time Fourier transform (STFT) program, short-time Fourier transform can be obtained non-stationary signal frequency diagram, the main principle is the interception of a signal with a sliding window that within this period of time the signal is stationary, access to spectrum fft transform them)

说明：  BV调度算法，在MATLAB上的实现，是源程序(BV scheduling algorithm in MATLAB)

语音mfcc特征参数提取matlab代码，粘贴在Word中，希望对大家有用(mfcc)

用matlab编写的猜数字有些，希望对大家有用。(Prepared using matlab numberguess some hope for all of us.)

说明：  使用ziegler方法，对PID控制器进行PID整定。(Using Ziegler method, the PID controller is tuned.)
