Distortion optimal transmission of multi-layered FGS video over wireless channels
Abstract-- We identify an analytical expression for the distortion of a scalable video bitstream containing a Base Layer (BL) and one or more Enhancement Layer (EL) bitstreams. Con...

Distributed one bit feedback extended orthogonal space time coding based on selection of cyclic rotation for cooperative relay n
In this paper, a novel closed-loop distributed extended orthogonal space time block code (D-EO-STBC) with one-bit feedback based on selection of phase rotation is proposed for two...

Improved Linear Distinguishers for SNOW 2.0
In this paper we present new and more accurate estimates of the biases of the linear approximation of the FSM of the stream cipher SNOW 2.0. Based on improved bias estimates we als...
