A survey on deep learning based joint source-channel coding
Dianxin 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 ...

EURASIP 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]
2010 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

Joint source-channel coding with adaptation [PDF]
2016 IEEE Sixth International Conference on Communications and Electronics (ICCE), 2016 According to Shannon's source-channel separation theorem, the source coding and the channel coding operations should be performed independently. However, such a method does not exploit the nature of unequiprobable source output in a finite block regime so that it can not achieve good qualities in several scenarios in practical systems.

Joint source-channel coding for a quantum multiple access channel [PDF]
, 2012 Suppose that two senders each obtain one share of the output of a classical, bivariate, correlated information source. They would like to transmit the correlated source to a receiver using a quantum multiple access channel. In prior work, Cover, El Gamal,

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

Inter-node compression with LDPC joint source–channel coding for highly correlated sources
Automatika, 2022 This paper investigates a new communication system where two nodes want to disseminate highly correlated contents to a single destination and can be applied for densely deployed wireless sensors networks applications.

Lossy joint source-channel coding in the finite blocklength regime [PDF]
, 2012 This paper finds new tight finite-blocklength bounds for the best achievable lossy joint source-channel code rate, and demonstrates that joint source-channel code design brings considerable performance advantage over a separate one in the non-asymptotic ...

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