Bandwidth-Agile Image Transmission With Deep Joint Source-Channel Coding [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2020
We propose deep learning based communication methods for adaptive-bandwidth transmission of images over wireless channels. We consider the scenario in which images are transmitted progressively in layers over time or frequency, and such layers can be ...

Reordered Elias Gamma Error Correction Codes for the Near-Capacity Transmission of Multimedia Information

open access: yesIEEE Access, 2016
A novel joint source and channel coding (JSCC) scheme is proposed, which we refer to as the reordered Elias gamma error correction (REGEC) code. Like the recently proposed unary error correction (UEC) code and EGEC code, the proposed code facilitates the

Achievable rate region for three user discrete broadcast channel based on coset codes [PDF]

open access: yes, 2015
We present an achievable rate region for the general three user discrete memoryless broadcast channel, based on nested coset codes. We characterize 3-to-1 discrete broadcast channels, a class of broadcast channels for which the best known coding ...

Nested turbo codes for the costa problem [PDF]

open access: yes, 2008
Driven by applications in data-hiding, MIMO broadcast channel coding, precoding for interference cancellation, and transmitter cooperation in wireless networks, Costa coding has lately become a very active research area.

Channel Coding and Source Coding With Increased Partial Side Information

open access: yesEntropy, 2017
Let ( S 1 , i , S 2 , i ) ∼ i . i . d p ( s 1 , s 2 ) , i = 1 , 2 , ⋯ be a memoryless, correlated partial side information sequence. In this work, we study channel coding and source coding problems where the partial side

A coding scheme for wireless networks with multiple antenna nodes and no channel information [PDF]

open access: yes, 2007
In this paper, we present a coding strategy for wireless relay networks where the relay nodes are small devices with few resources, while the source and sink are equipped with multiple antennas to increase the transmission rate.

DeepJSCC-f: Deep Joint Source-Channel Coding of Images With Feedback [PDF]

open access: yesIEEE Journal on Selected Areas in Information Theory, 2019
We consider wireless transmission of images in the presence of channel output feedback. From a Shannon theoretic perspective feedback does not improve the asymptotic end-to-end performance, and separate source coding followed by capacity-achieving ...

On the Separation of Lossy Source-Network Coding and Channel Coding in Wireline Networks [PDF]

open access: yes, 2010
This paper proves the separation between source-network coding and channel coding in networks of noisy, discrete, memoryless channels. We show that the set of achievable distortion matrices in delivering a family of dependent sources across such a ...

Overview of the challenges and solutions for 5G channel coding schemes

open access: yesJournal of Information and Telecommunication, 2021
5G is the next generation of mobile communications networks which will use cutting-edge network technologies to deliver enhanced mobile connectivity. 5G has introduced new requirements for channel coding in its three different service classes which are ...

High-Rate Permutation Coding with Unequal Error Protection [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2022
Channel coding provides numerous advantages to digital communications. One of such advantages is error correcting capabilities. This, however, comes at the expense of coding rate, which is a function of the codebook’s cardinality |C| or number of coded ...
