生成正弦波，不需要调用sin函数，利用的查表法(Generate a sine wave, you do not need to call the sin function using table look-up method)

PCM linear system designed on Simulink

Matlab入门学习，包括源程序，word文档已解密。(Matlab entry-learning, including source code, word documents decrypted.)

导入振动信号（2信道）分析时域、频域波形的MATLAB-GUI界面(Import vibration signals (2-channel) analysis in time domain and frequency domain by MATLAB-GUI interface)

用matlab实现的曼彻斯特 XGTmWM编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的sBffqAy 的通信原理课件上的形状一模一样。 .(With Manchester XGTmWM encoding matlab realize. 50 duty cycle (adjustable) . Draw time-domain waveform and frequency domain power spectral density. Results with BUPTsBffqAy Exactly the same shape Wenbin communication on the principles of courseware.)

说明：  一个用matlab编写的贪婪算法程序，可以嵌入到其他程序中(Matlab prepared a greedy algorithm procedures, can be embedded in other procedures)

Extreme Programming Applied介绍具体实施xp方法的流程以及需要注意的问题。(Extreme Programming Applied introduce specific implementation methods xp processes and the need to pay attention to.)

1. 采用增量式 PID控制算法实现该系统的稳定控制 2. 采用Z—N整定PID参数(1. An incremental PID control algorithm to achieve the system' s stability control 2. Using Z-N tuning PID parameters)

说明：  波束形成中利用ML算法实现自适应波束形成的matlab代码(ML beamforming using adaptive beamforming algorithm matlab code)

..Barcode analysis based on webcam.. this program is an example how to extracting features of the barcode and analyze them,,, for example we can use webcam to get the barcode image.
