自己编的，基于自适应噪声对消的语音增强新算法(Own, based on adaptive noise cancellation of the new algorithm for speech enhancement)

说明：  matlab code for finger print detection

说明：  CRC校验码的Matlab源程序,希望对大家有帮助(CRC check code Matlab source, I hope to help you)

简单的绘图示例程序，matlab作业中的要求(Example of a simple drawing program, matlab operations requirements)

matlab programs from constantine balanis antenna theory

说明：  滤波方法的通用，值得大家学习 还可以在此基础上改进(Universal filter, is worth learning can be improved on this basis)

说明：  信号处理,进行信号检测与处理，通过设定threshold来进行信号检测的可信度调整(Credibility adjustment signal processing, signal detection and processing, by setting threshold for signal detection)

利用MATLAB进行带通数字调制与解调——M元正效幅度键控调制。(we use MATLAB for bandpass digital modulation and demodulation- M Yuan positive effect amplitude shift keying modulation to achive a good understanding.)

这个主要设计了一个butterworth 滤波器 实现滤波效果(this is used to lvbo and design a butterworth )
