On Achievable Distortion in Sending Gaussian Sources over a Bandwidth-Matched Gaussian MAC with No Transmitter CSI

open access: yesEntropy, 2019
This paper investigates the minimum mean square error (MMSE) of communicating a pair of Gaussian sources over a a bandwidth-matched Gaussian multiple-access channel with block Rayleigh fading in the absence of channel state information (CSI) at the ...

A survey on deep learning based joint source-channel coding

open access: yesDianxin kexue, 2020
Classical information theory shows that separate source-channel coding is asymptotically optimal over a point-to-point channel.As modern communication systems are becoming more sensitive to delays and bandwidth,it becomes difficult to adopt the ...

Distributed Joint Source-Channel Coding-Based Adaptive Dynamic Network Coding

open access: yesIEEE Access, 2020
Distributed Source Coding (DSC) schemes rely on separate encoding but joint decoding of statistically dependent sources, which exhibit correlation. More specifically, Distributed Joint Source-Channel coding (DJSC) is associated with the scenario, where ...

Joint source-channel coding for image transmission based on best wavelet packet

open access: yesTongxin xuebao, 2012
A novel joint source/channel image coding algorithm was proposed based on the best wavelet packet in a rate-distortion sense.Different from other wavelet packet image coding,the channel and the channel code information were introduced to the source ...

Cross-Layer Design for Video Transmission over Wireless Rician Slow-Fading Channels Using an Adaptive Multiresolution Modulation and Coding Scheme

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
We describe a multilayered video transport scheme for wireless channels capable of adapting to channel conditions in order to maximize end-to-end quality of service (QoS).

Polar codes for channel and source coding

open access: yes, 2009
The two central topics of information theory are the compression and the transmission of data. Shannon, in his seminal work, formalized both these problems and determined their fundamental limits. Since then the main goal of coding theory has been to find practical schemes that approach these limits.

Design of superposition polar coding for binary-input less-noisy broadcast channels

open access: yesICT Express, 2017
In this study, we design a superposition polar code that can achieve the capacity region of binary-input less-noisy broadcast channels asymptotically. Simulation results show that a better rate region is achievable by superposition polar coding than by ...
