Particle Swarm Optimization Of Fuzzy Penalty For 3D Image Reconstruction In X-Ray Tomography

Mohamed Tahar Ali Gouicem, Mostepha Yahi, Abdelmalik Taleb-Ahmed, Redouane Drai

Engineers last year's works only on the 2D image data, to perceive defects in the CT images. This was a handicap facing the challenge of determining the 3D exact defect form. This paper presents a method for 3D image reconstruction, the most interesting in non destructive testing (NDT)…

Joint semi-blind estimation of CFO and channel for OFDM system

Mokhtar Besseghier, Ahmed Bouzidi Djebbar, Iyad Dayoub, Abdelmalik Taleb-Ahmed

The greatest threat to the OFDM system is the loss of orthogonality between subcarriers due to the carrier frequency offset (CFO) which results in significant performance degradation. In addition to this last problem was the effect of propagation over multipath fading channel. Hence, both the…
