使用matlab的小波分解和重建函数对24位的ADC采样数据进行小波变换和去噪，去噪使用阈值算法，阈值的选取具体使用了6种方法进行对比，对于不同信号其效果是不同的！把去噪后的信号和原始信号放在一个图中，使用不同颜色的曲线进行对比，效果可以很直观的表现。(Using matlab wavelet decomposition and reconstruction of the function for 24-bit ADC sampling data wavelet transform and denoising, denoising using the threshold algorithm, the threshold selecting specific methods used six kinds of contrast, the effect for different signals is different The! After the denoising signal and the original signal on a map using different colors to compare curves, the effect can be very intuitive performance.)

2ask的调制解调以及matlab仿真，包括频谱分析等(2ask the modem and the matlab simulation, including spectral analysis)

生物医学信号处理方面的IEEE文章，主要是研究ECG（心电信号）的，比较有价值(biomedical signal processing IEEE article, it is mainly the research ECG (ECG), quite valuable)

仿真FFT参数对采用FFT算法分析信号频谱的影响。产生频率分别为2Hz，2.05Hz的正弦波合成信号，采样频率＝10Hz。(Simulation of the influence of FFT parameters on the frequency spectrum of the signal using FFT algorithm analysis. The frequency of sine wave synthesis are respectively 2Hz, 2.05Hz signal, the sampling frequency is 10Hz.)

pnn分类器算法，用MATLAB源码，可以进行分类。(pnn classifier algorithm, using MATLAB source code can be classified.)
