认知无线电能量检测法的仿真及其源代码和简要说明(Simulation of Energy Detection of cognitive radio )

利用模拟Butterworth滤波器设计数字低通滤波器！(Analog filter design using Butterworth digital low-pass filter!)

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)

使用频域平滑的方法来实现信号循环谱估计的算法(The smooth frequency domain signal cyclic spectrum estimation algorithm)

This MATLAB code simulates the (15,11) Hamming Code.

介绍matlab线性函数的应用，并包含许多经典的例子(Introduced a linear function of matlab)

基于高斯滤波器的图像压缩算法。可以处理真彩图和灰度图，相当实用。(Gaussian filter based on image compression algorithms. Can handle true color pictures and grayscale, quite useful.)

说明：  求最小值的方程原文件及运行命令文件，可以方便快捷的求出非线性有约束的最小值(Seeking the minimum value of the equation of the original documents and run the command file, you can find convenient and efficient non-linear constrained minimum)

说明：  用正弦分析方法对语音进行分析和处理的matlab程序，对初学者有用(Analysis method using sinusoidal speech analysis and processing matlab program, useful for beginners)

EMD的边际谱的算例，很实用，做这一块的快下(EMD example the marginal spectrum, it is practical to do this under a piece of the fast)
