Distributed Joint Source-Channel Coding Using Quasi-Uniform Systematic Polar Codes [PDF]

open access: yesEntropy, 2018
This paper proposes a distributed joint source-channel coding (DJSCC) scheme using polar-like codes. In the proposed scheme, each distributed source encodes source message with a quasi-uniform systematic polar code (QSPC) or a punctured QSPC, and only ...

Channel-Blind Joint Source–Channel Coding for Wireless Image Transmission [PDF]

open access: yesSensors
Joint source–channel coding (JSCC) based on deep learning has shown significant advancements in image transmission tasks. However, previous channel-adaptive JSCC methods often rely on the signal-to-noise ratio (SNR) of the current channel for encoding ...

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

Transmission of Still Images Using Low-Complexity Analog Joint Source-Channel Coding [PDF]

open access: yesSensors, 2019
An analog joint source-channel coding (JSCC) system designed for the transmission of still images is proposed and its performance is compared to that of two digital alternatives which differ in the source encoding operation: Joint Photographic Experts ...

Distributed Joint Source-Channel Coding in Wireless Sensor Networks [PDF]

open access: yesSensors, 2009
Considering the fact that sensors are energy-limited and the wireless channel conditions in wireless sensor networks, there is an urgent need for a low-complexity coding method with high compression ratio and noise-resisted features.

Zero-Delay Joint Source Channel Coding for a Bivariate Gaussian Source over the Broadcast Channel with One-Bit ADC Front Ends [PDF]

open access: yesEntropy, 2021
In this work, we consider the zero-delay transmission of bivariate Gaussian sources over a Gaussian broadcast channel with one-bit analog-to-digital converter (ADC) front ends. An outer bound on the conditional distortion region is derived.

Natural chunk-and-pass language processing: Just another joint source-channel coding model? [PDF]

open access: yesCommunicative & Integrative Biology, 2018
A recent theoretical treatment by Christiansen and Chater attempts to address fundamental challenges significant to language processing and evolution with one major operational constraint called the “Now-or-Never” bottleneck. The authors' “Chunk-and-Pass”

PAC Codes for Source and Joint Source-Channel Coding

open access: yes2023 IEEE Globecom Workshops (GC Wkshps), 2023
Polarization-adjusted convolutional (PAC) codes, as a concatenated coding scheme based on polar codes, is able to approach the finite-length bound of binary-input AWGN channel at short blocklengths. In this paper, we extend PAC codes to the fields of source coding and joint source-channel coding and show that they can also approach the corresponding ...
