Turbo编码技术及其在移动通信中的应用研究(Turbo coding technology and its application in mobile communication research)

本程序实现haar小波的变换，在图像去噪。压缩等方面有很大的帮助(This procedure to achieve haar wavelet transform, the image de-noising. Compression there is a great help)

根据已给ecg数据文件，画出心电图波形，并自动标记出特征点位置，并计算P-R时间间隔 等参数。 附件是.dat为数据文件，为二进制文件，每2个字节代表一个采样点，采样频率1000hz。依 次为1-12导联的第一个采样点，其次是1-12导联第二个采样点，.... .hea头文件是文本格式说明文件，可以看到十二导联存放的先后顺序。 (According to the data file has to ecg, draw the ECG waveform, and automatically mark the feature points, and calculate parameters such as PR interval. The attachment is. Dat for data files, binary files, each 2 bytes represent a sampling point, the sampling frequency 1000hz. Followed by a 1-12 lead in the first sampling point, followed by 1-12 second sampling point lead ,..... Hea header file is a text file format that you can see the sequence)

贝叶斯阈值方法实现图像去噪，对文献Chang.adaptive wavelet thresholding for image denoising and compression仿真结果。(Bayesian threshold method of image denoising。)

Least squares sinusoid fit algorithm described in IEEE Standard for Digitizing Waveform Recorders (IEEE Std 1057): Algorithm for three-parameter and four-parameter least squares fit to sinewave data using matrix operations. The algorithm is (in most cases) really quick. If the signal frequency is a guess, it has to be close to true frequency value. For further information, consult IEEE Std 1057 and/or IEEE Std 1241 documentation. Now also fits complex sinusoids i.e. phasors with noise and o
