基于随机共振的弱信号检测，sr为龙格库塔方法解方程，rs为检测的主程序(Based on stochastic resonance in weak signal detection, sr for the Runge-Kutta method to solve the equation, rs for the detection of the main program)

设模拟带通信号频率范围1KHz—1.1KHz，设计一个采样频率8KHz数字频谱分析系统，要求频率分辨率0.1Hz。若对信号直接用FFT进行频谱分析(simulation based communications, with the frequency range 1KHz- 1.1KHz. Design of an 8 KHz sampling frequency digital spectrum analysis system requirements frequency resolution 0.1 Hz. If the signal directly FFT spectrum analysis)

Intelligent Fault Diagnosis and Prognosis for Engineering Systems

通过matlab仿真说明从音频中提取背景音乐的方法，并通过dsp实现(Matlab simulation shows that by extracting from the audio background music of the method, and achieved through the dsp)

很多经典的音频水印程序,有一些可直接使用，有一些需要调试使用(many classic audio watermarking matlab program)

it s a tiny code.i m looking forward to help someone

说明：  这是一份关于瑞利和莱斯衰落信道的matlab代码(Rayleigh and Rice Fading Channel)

对基于软件无线电的gps系统进行了完整论述，介绍gps系统软件接收机的最新研究成果的时机已经成熟，同时介绍即将投入使用的欧洲伽利略导航系统。利用matlab(版本7．x)作为编程语言，其提供了非常强大的绘图功能，可以直观清楚地显示数据的结果。(Gps software radio-based system for a complete discussion of system software gps receiver introduces the latest research results of the time is ripe, will soon also introduced into the European Galileo navigation system to use. Using matlab (version 7.x) as a programming language, it provides a very powerful graphics capabilities, you can visually display the data the results clearly.)

DFT in matlab, the code is a example of long time in computation.

说明：  读取MIT BI心电数据库文件，使用matlab编程，(MIT BI read ECG database file, use the matlab programming,)
