Information Capacity and BER Improvement Using Haar Transform in DWT-CDMA Water Marking Based on Pseudorandom Sub Space Projection
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 11
Abstract
In this paper we remove the host image correlation with the a orthogonal sequence during extracting phase is proposed in high capacity CDMA watermarking which improves the BER, message capacity, and robustness of watermarking scheme .this elimination is implemented in steps using projections and different noises are added and filtered. Finally BER is improved compared to existing scheme
