Near-capacity dirty-paper code design : a source-channel coding approach [PDF]
, 2009 This paper examines near-capacity dirty-paper code designs based on source-channel coding. We first point out that the performance loss in signal-to-noise ratio (SNR) in our code designs can be broken into the sum of the packing loss from channel coding ...

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 ...

Joint source-channel coding with inner irregular codes [PDF]
2008 IEEE International Symposium on Information Theory, 2008 We address the optimization of joint source-channel coding schemes for iterative source-channel decoding of first- order Markov sources. Compared to the traditional design, we propose two novelties: (1) source encoders, providing code words with a minimum Hamming distance dminges2, realized by linear block codes, and (2) irregular channel encoders ...

Iterative channel equalization, channel decoding and source decoding [PDF]
, 2005 The performance of soft source decoding is evaluated over dispersive AWGN channels. By employing source codes having error-correcting capabilities, such as Reversible Variable-Length Codes (RVLCs) and Variable-Length Error-Correcting (VLEC) codes, the ...

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.

Iteratively Decoded Irregular Variable Length Coding and Trellis Coded Modulation [PDF]
, 2007 In this paper we propose a novel Irregular Variable Length Coding (IrVLC) scheme for near-capacity joint source and channel coding. We employ a number of Variable Length Coding (VLC) component codebooks having different coding rates for encoding ...

Distributed Joint Source-Channel Coding for Relay Systems Exploiting Source-Relay Correlation and Source Memory [PDF]
, 2012 In this article, we propose a distributed joint source-channel coding (DJSCC) technique that well exploits source-relay correlation as well as source memory structure simultaneously for transmitting binary Markov sources in a one-way relay system.

Neural Joint Source-Channel Coding
, 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
