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

On adversarial joint source channel coding [PDF]

open access: yes2015 IEEE International Symposium on Information Theory (ISIT), 2015
In a joint source-channel coding scheme, a single mapping is used to perform both the tasks of data compression and channel coding in a combined way, rather than performing them separately. Usually for simple iid sources and channels, separation of the tasks is information theoretically optimal.

An Overview on Wavelets in Source Coding, Communications, and Networks

open access: yesEURASIP Journal on Image and Video Processing, 2007
The use of wavelets in the broad areas of source coding, communications, and networks is surveyed. Specifically, the impact of wavelets and wavelet theory in image coding, video coding, image interpolation, image-adaptive lifting transforms, multiple ...

Neural Joint Source-Channel Coding

open access: yes, 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

Source-Channel Diversity for Parallel Channels

open access: yes, 2004
We consider transmitting a source across a pair of independent, non-ergodic channels with random states (e.g., slow fading channels) so as to minimize the average distortion. The general problem is unsolved. Hence, we focus on comparing two commonly used

Joint Source and Channel Decoding for Variable Length Encoded Turbo Codes

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
Joint source and channel decoding (JSCD) has been proved to be an effective technique which can improve decoding performance by exploiting residual source redundancy.

Distributed Hypothesis Testing over a Noisy Channel: Error-Exponents Trade-Off

open access: yesEntropy, 2023
A two-terminal distributed binary hypothesis testing problem over a noisy channel is studied. The two terminals, called the observer and the decision maker, each has access to n independent and identically distributed samples, denoted by U and V ...

Joint Source-Channel Coding with Time-Varying Channel and Side-Information [PDF]

open access: yes, 2015
Transmission of a Gaussian source over a time-varying Gaussian channel is studied in the presence of time-varying correlated side information at the receiver.

Lossy Joint Source-Channel Coding Using Raptor Codes

open access: yesInternational 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.
