Checksum-Filtered List Decoding Applied to H.264 and H.265 Video Error Correction

Firouzeh Golaghazadeh, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay

The latest video coding standards, H.264 and H.265, are highly vulnerable in error-prone networks. Reconstructed packets may exhibit significant degradation in terms of peak signal-to-noise ratio and visual quality. This paper presents a novel list-decoding approach exploiting the receiver side…

Improved Eigenfilter Design Method for Channel Shortening Equalizer in TH-UWB

Noureddine Benamara Benotmane, Sid Ahmed Elahmar, Iyad Dayoub, Walaa Hamouda

The large delay spread of ultra-wideband (UWB) channels causes intersymbol interference and therefore increases the complexity of a UWB Rake receiver. To resolve these problems, we present a new method for the design of channel shortening equalizers (CSE) in time-hopping UWB systems. Our proposed…

Modeling and optimization of core (p-GaN)-multishell (i-InxGa1-xN/i-GaN/n-Al0.1Ga0.9N /n-GaN) nanowire for photovoltaic applications

Abdelkader Aissat, Fethi Benyettou, Isabelle Berbezier, Jean-Pierre Vilcot

In this work we report a modeling and optimization of a novel core (p-GaN)-multishell (i-InxGa1-xN/i-GaN/n-Al0.1Ga0.9N/n-GaN) coaxial NWs with a total length of about 3 μm and a radius of 0.19 μm. The variation of Indium composition in the i-InxGa1-xN active layer shows that x = 15% is the optimal…

Room temperature pulsed-DC sputtering deposition process for CIGS absorber layer: Material and device characterizations

Boubakeur Ayachi, Thomas Aviles, Jean-Pierre Vilcot, Cathy Sion, Patrice Miska

A pulsed-DC sputtering process at room temperature has been developed for the deposition of the CIGS absorber layer. It uses a single quaternary target and is followed by a high temperature post-deposition annealing process. It has to be particularly noticed that no additional selenium supply was…
