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

IEEE 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

Learning to Compress Over Arbitrary Channels: Information Bottleneck-Based Distributed Joint Source-Channel Coding via Deep MARL

IEEE Open Journal of the Communications Society
In this article, we introduce a Reinforcement Learning (RL)–driven framework for Information Bottleneck (IB)–based distributed Joint Source–Channel Coding (JSCC) that operates reliably when the forward channels are unknown, non ...

An Efficient and Robust Three-Dimensional Semantic Index Modulation Visible Light Communication System for Image Transmission

Tongxin xuebao
Deep semantic communication (Deep JSCC) alleviates the cliff effect of conventional VLC-OFDM under harsh channels, but lacks physical-layer constraints, resulting in high PAPR and LED nonlinearity.

Energy-Efficient Autoencoder-Based Compact Image Payload Transmission over Noisy Indoor Industrial VLC Links

Photonics
Visible light communication (VLC) can reduce radio-frequency (RF) congestion in indoor industrial monitoring, but a short transmitted payload does not by itself prove that visual or task-relevant information has been preserved.

Exploiting 2-dimensional source correlation in channel decoding with parameter estimation for unknown source [PDF]

, 2018
Source redundancy does not contain any significant information for transmission in a communication system and therefore, one of the approaches to overcome this issue is by exploiting the source redundancy for error-correction via Joint Source Channel ...

A NOVEL JSCC SCHEME FOR SCALABLE VIDEO TRANSMISSION OVER MIMO SYSTEMS

, 2012
MIMO recently emerges as one of promising techniques for wireless video streaming. It is still a challenge to provide un-equal error protections by joint source-channel coding (JSCC) over multiple diverse MIMO sub-channels.
