Joint Source-Channel Coding for Wavelet-Based Scalable Video Transmission Using an Adaptive Turbo Code

open access: yesEURASIP Journal on Image and Video Processing, 2007
An efficient approach for joint source and channel coding is presented. The proposed approach exploits the joint optimization of a wavelet-based scalable video coding framework and a forward error correction method based on turbo codes.

Distributed joint source-channel arithmetic coding [PDF]

open access: yes2010 IEEE International Conference on Image Processing, 2010
We address distributed source coding with decoder side information, when the decoder observes the source through a noisy channel. Existing approaches employ syndromeor parity-based channel codes. We propose a new approach based on distributed arithmetic coding (DAC).We introduce a DAC with forbidden symbol, which allows to tune the redundancy according

Analysis and Optimization of a General Linking Matrix for JSCC Scheme Based on Double LDPC Codes

open access: yesEntropy, 2023
A key component of the joint source-channel coding (JSCC) scheme based on double low-density parity-check (D-LDPC) codes is the introduction of a linking matrix between the source LDPC code and channel LDPC code, by which the decoding information ...

Neural Joint Source-Channel Coding

open access: yes, 2018
For reliable transmission across a noisy communication channel, classical results from information theory show that it is asymptotically optimal to separate out the source and channel coding processes. However, this decomposition can fall short in the finite bit-length regime, as it requires non-trivial tuning of hand-crafted codes and assumes infinite

Joint source–channel rate allocation with unequal error protection for space image transmission

open access: yesInternational Journal of Distributed Sensor Networks, 2017
High reliable and efficient image transmission is of primary importance for space communications. In the traditional space image transmission system design, the source coding module and channel coding module are separated.

LDGM Codes for Channel Coding and Joint Source-Channel Coding of Correlated Sources

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We propose a coding scheme based on the use of systematic linear codes with low-density generator matrix (LDGM codes) for channel coding and joint source-channel coding of multiterminal correlated binary sources. In both cases, the structures of the LDGM

Joint Source and Channel Decoding for Variable Length Encoded Turbo Codes

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
Joint source and channel decoding (JSCD) has been proved to be an effective technique which can improve decoding performance by exploiting residual source redundancy.

Joint Source-Channel Coding at the Application Layer [PDF]

open access: yes2009 Data Compression Conference, 2009
The multicasting of an independent and identically distributed Gaussian source over a binary erasure broadcast channel is considered. This model applies to a one-to-many transmission scenario in which some mechanism at the physical layer delivers information packets with losses represented by erasures, and users are subject to different erasure ...
