Analog Joint Source Channel Coding Using Space-Filling Curves and MMSE Decoding
We investigate the performance of a discrete-time all-analog-processing joint sourcechannel coding system for the transmission of i.i.d. Gaussian and Laplacian sources over AWGN c...

Subjective Quality Evaluation of Decoded Video in the Presence of Packet Losses
This paper investigates the perceptual quality of decoded video bitstreams after packet losses. We focus on lowresolution and low-bit rate video coded by the H.264/AVC encoder, an...

Decoders for low-density parity-check convolutional codes with large memory
— Low-density parity-check convolutional codes offer the same good error-correcting performance as low-density parity-check block codes while having the ability to encode and dec...

Joint source-channel coding of binary sources with side information at the decoder using IRA codes
— We use systematic irregular repeat accumulate (IRA) codes as source-channel codes for the transmission of an equiprobable memoryless binary source with side information at the ...
