Wavelet-Based Spread Spectrum Communications

چکیده
| A multiple access communication scheme using wavelet-based orthogonal codes is described. The message bit stream in each channel is encoded as a sequence of time-shifted replicates of a mother wavelet symbol at a particular scale. Diierent channels use the same wavelet symbol but a diierent scale. The messages are decod-able if the time-shifted and dilated replicates of the wavelet symbol used in the encoding are orthogonal. Variations, potential applications, and construction of suitable wavelets for use with this scale-division multiple access scheme in low probability of exploitation communication systems are discussed.

Fully Robust Spread Spectrum Wavelet Watermarking System
Existing spread spectrum based watermarking techniques can not despread the encoded signal as expected in a typical spread spectrum communication system. Also the change in the statistics of the watermarked image as a result of attacks are not adequately compensated. It is therefore expected that these systems have not yielded the desired fully robust characteristics. This paper presents a spre...
متن کاملRedundant Wavelet Watermarking using Spread Spectrum Modulation
Spread Spectrum modulation has become a preferred paradigm in many watermarking applications. This paper analyzes the performance of such a blind watermarking scheme under discrete wavelet frame rather than a traditional orthonormal wavelet expansion. The over complete representation offered by the redundant frame facilitates the identification of significant image features via a simple correla...

This paper proposes an oblivious watermarking algorithm with blind detection approach for high volume data hiding in image signals. We present a detection reliable signal adaptive embedding scheme for multiple messages in selective sub-bands of wavelet (DWT) coefficients using direct sequence spread spectrum (DS-SS) modulation technique. Here the impact of volumetric distortion sources is analy...

This paper proposes a robust spread spectrum based audio watermarking scheme using Discrete wavelet transform (DWT). Here we use a peak detection algorithm to obtain high robustness. In this watermarking scheme, watermarks are embedded into the peak value of detail coefficients of, transformed audio signal. It is a blind watermarking technique which is used for providing copyright protection an...
متن کاملOptimum decoder for multiplicative spread spectrum image watermarking with Laplacian modeling
This paper investigates the multiplicative spread spectrum watermarking method for the image. The information bit is spreaded into middle-frequency Discrete Cosine Transform (DCT) coefficients of each block of an image using a generated pseudo-random sequence. Unlike the conventional signal modeling, we suppose that both signal and noise are distributed with Laplacian distribution, because the ...
