In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique. As with other spread spectrum technologies, the transmitted signal takes up more bandwidth than the information signal that modulates the carrier or broadcast frequency. The name spread spectrum comes from the fact that the carrier signals occur over the full bandwidth (spectrum) of a device s transmitting frequency.

taup 变换MATLAB代码 可以自己修改(taup transform MATLAB code can make changes to)

matlab制作的数字水印算法原程序，实现整个程序运行还行，共享给大家-jpeg of the Matlab Simulation, and the whole process has run OK, for everyone to share (matlab digital watermarking algorithm produced the original procedure, also realize the whole process to run line-sharing to the U.S.-jpeg of the Matlab Simulation, and the whole process has run OK, for everyone to share)

说明：  数字水印的matlab程序，本程序是基于matlab的程序，对数字水印可以较好地实现水印图片的提取(Digital watermarking matlab program, this program is a matlab-based procedures, the digital watermark can be better achieved the watermark image extraction)
