Filters Ranking for DWT-Domain Robust Digital Watermarking
EURASIP Journal on Advances in Signal Processing, 2004 In recent years a number of wavelet-based watermarking schemes have been proposed and exhibited improved qualities. The choice of a wavelet filter bank for a digital watermarking scheme can have a significant influence on the scheme's performance in ...

Spread Spectrum from Two Perspectives [PDF]
SIAM Review, 2003 Summary: Spread spectrum techniques are often employed when transmitting information. They are widely used in wireless and cellular telephony. Spread spectrum techniques allow one to partition bandwidth, to hide transmissions, and to protect one's transmissions from being jammed. In this article, we develop two facets of spread spectrum. We show how to

Speech Bandwidth Extension Using DWT-FFT-Based Data Hiding [PDF]
Radioengineering, 2020 A novel transform-domain speech bandwidth extension algorithm is proposed to transmit information about the missing speech frequencies over a hidden channel, i.e., the related encoded spectral envelope parameters are hidden within the narrowband speech ...
