移相全桥DC-DC控制电路仿真

余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

说明：  通过matlab实现iir bandpass滤波器(iir bandpass)

preconditioned gradient algorithm for iterative solution

Encoding of LDPC codes

在matlab中编制Levy法辨识程序并进行测试(Identification procedures for the preparation of the Levy method in matlab and tested)

说明：  matlab code for finger print detection

This MATLAB program calculate the fractal dimension using Higuchi method.It also show its relationship with the theoretical values.

This File calculate spectral correlation function of cyclostationary signal based on frequency smoothing.

拉东变换 用MATLAB程序实现的 对拉东变换感兴趣的朋友可以来顶一下。。。。多多支持哦。。。。。。(Radon Transform using MATLAB program on Radon Transform Friend interested can come to the top look. . . . Oh, a lot of support. . . . . .)
