In this paper a class of detector for optimal watermark detection is presented. It operates in the frequency domain, based on the pdf modeling. The new class of detectors can improve accuracy, as compared with standard Gaussian models. The experimental results support theoretical consideration.
A new scalable video coding based DCT-DWT temporal and spatial transform has been proposed in this paper. The DCT transform reduces the inter-frame redundancy and the DWT transform reduces the intra-frame redundancy. ...

This paper presents a nonlinear echo canceller implementation running on a digital signal processor (DSP). A nonlinear channel is equalized, by using a set of linear dynamic system followed by a nonlinear static map. The proposed scheme is implemented on a general purpose DSP with floating point arithmetic.

In this paper, the wavelet lifting principle has been used in signal compression and de-noising. This is achieved, through the optimal choice of the orthogonal basis and lifting parameters of a biorthogonal system, designed to minimize either the entropy or the dynamic range of the coefficients of the wavelet packet decomposition of the signal to be compressed. Illustrative examples are given to verify the proposed methods.
In this paper, a new frequency offset compensation scheme for up link of multicarrier code-division multiple access (MC-CDMA) systems is proposed. The proposed scheme exploits guard interval (GI) information embedded ...

This paper studies the performance of the vector channel probing method with feedback. The least squares (I-S), minimum mean square error (MMSE), and a new scaled LS (SLS) approaches to the channel estimation are studied. Optimal choice of probing signals is investigated for each of these techniques.
We address the problem of multiuser signal detection in the presence of additive non-Gaussian noise, particularly the numerical procedure for solving m-equations. When the noise is modelled by the e-contaminated mixtu...
