چکیده

This work advocates the formulation of digital watermarking as a communication problem. We consider watermark-ing as communication with side information available for both encoder and decoder. A generalized watermarking channel is considered that includes geometrical attacks, fading and additive non-Gaussian noise. The optimal encod-ing/decoding scenario is discussed for the generalized watermarking channel.

Watermarking with diversity: insights and implications - Multimedia, IEEE

communication theory tool sets based on diversity and channel estimation improves the performance of robust digital watermarking algorithms. This article demonstrates that algorithms employing some form of watermark redundancy can be significantly enhanced. It also discusses effective data-hiding strategies within the proposed framework and reports on the results of robust reference watermarkin...

Capacity of Rayleigh Fading Channels Under Different Adaptive Transmission and Diversity-Combining Techniques

We study the Shannon capacity of adaptive transmission techniques in conjunction with diversity combining. This capacity provides an upper bound on spectral efficiency using these techniques. We obtain closed-form solutions for the Rayleigh fading channel capacity under three adaptive policies: optimal power and rate adaptation, constant power with optimal rate adaptation, and channel inversion...
