模糊函数

对于IEC谐波检测的程序，采用hanning窗函数，然而求解(For the IEC harmonic detection process, using hanning window function, but the solution)

Its a IEEE Pesgm 08 paper.

高阶累积量，用于信号的调制识别，性能较好(high order cumulant,used to AMC.)

Simulation for sampling of frequency

Matlab Function to analytically calculation of a frequency of a signal

BPSK simulation using a carrier cosine wave with ISI

MULTILETARION FOR TRACKING

该程序利用matlab实现levinson_durbin算法(The program utilizes Matlab levinson_durbin algorithm)

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)
