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

Joint source and turbo trellis coded hierarchical modulation for context-aware medical image transmission [PDF]

, 2013
An iterative Joint Source and Turbo Trellis Coded Hierarchical Modulation is introduced for robust context-aware medical image transmission. Lossless source compression as well as Quality of Service (QoS) might be considered as the main constraints in ...

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.

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 ...

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

EURASIP 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

On the performance and complexity of irregular variable length codes for near-capacity joint source and channel coding

, 2008
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 component Variable Length Coding (VLC) codebooks having different coding rates for encoding ...

Lossy Joint Source-Channel Coding Using Raptor Codes

International Journal of Digital Multimedia Broadcasting, 2008
The straightforward application of Shannon's separation principle may entail a significant suboptimality in practical systems with limited coding delay and complexity.

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

2009 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 ...

Results on combinatorial joint source-channel coding [PDF]

2012 IEEE Information Theory Workshop, 2012
This paper continues the investigation of the combinatorial formulation of the joint source-channel coding problem. In particular, the connections are drawn to error-reducing codes, isometric embeddings and list-decodable codes. The optimal performance for the repetition construction is derived and is shown to be achievable by low complexity Markov ...
