Wavelet Based Semi-blind Channel Estimation For Multiband OFDM
Sajad Sadough, Mahieddine Ichir, Emmanuel Jaffrot +1
This paper introduces an expectation-maximization (EM) algorithm within a wavelet domain Bayesian framework for semi-blind channel estimation of multiband OFDM based UWB communicat…

Bayesian Wavelet Based Signal and Image Separation
Mahieddine M. Ichir, Ali Mohammad-Djafari
In this contribution, we consider the problem of blind source separation in a Bayesian estimation framework. The wavelet representation allows us to assign an adequate prior distri…

Wavelet Domain Image Separation
Ali Mohammad-Djafari, Mahieddine Ichir
In this paper, we consider the problem of blind signal and image separation using a sparse representation of the images in the wavelet domain. We consider the problem in a Bayesian…
