Joint source-channel coding for cribbing models
2012 IEEE International Symposium on Information Theory Proceedings, 2012In this work we study problems of joint source-channel coding for the multiple access channel with cribbing encoders. These problems are motivated by modern communication scenarios such as an uplink channel for cellular users. Provided that the users are close enough to each other, they can causally crib to the output signals of their neighbours, thus ...

Dynamic joint source-Channel coding with feedback
2013 IEEE International Symposium on Information Theory, 2013This paper considers real time joint source-channel coding of a Markov source over a discrete memoryless channel with noiseless feedback. The encoder incurs a cost which is minimized along with a real-time end-to-end distortion. The problem is mapped to a partially observable Markov decision problem and the corresponding optimality equations, in the ...

Duality theorems for joint source-channel coding
IEEE Transactions on Information Theory, 2000Summary: We consider joint source-channel coding for a memoryless Gaussian source and an additive white Gaussian noise channel. For a given code defined by an encoder-decoder pair \((\alpha,\beta)\), its dual code is obtained by interchanging the encoder and decoder: \((\beta,\alpha)\). It is shown that if a code \((\alpha,\beta)\) is optimal at rate \(

Random-coding joint source-channel bounds
2011 IEEE International Symposium on Information Theory Proceedings, 2011Random-coding exact characterizations and bounds to the error probability of joint source-channel coding are presented. In particular, upper bounds using maximum-a-posteriori and threshold decoding are derived as well as a lower bound motivated by Verdu-Han's lemma.

Distributed joint source-channel coding of video
IEEE International Conference on Image Processing 2005, 2005Based on recent works on source-channel coding for Wyner-Ziv coding, we consider the case with noisy channel in Wyner-Ziv coding and address distributed joint source-channel coding, while targeting at the important application of video transmission over packet erasure channels.

Joint source-channel subband coding of images
1997 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2002This paper proposes a new adaptive source-channel coding scheme in the context of subband coding. We first express the total mean-squared distortion suffered by the source in terms of source and channel distortions of the subbands. We then minimize this total distortion by an appropriate choice of source and channel coding rates for the subbands.

Zero-delay joint source-channel coding
2014 Iran Workshop on Communication and Information Theory (IWCIT), 2014In zero-delay joint source-channel coding each source sample is mapped to a channel input, and the samples are directly estimated at the receiver based on the corresponding channel output. Despite its simplicity, uncoded transmission achieves the optimal end-to-end distortion performance in some communication scenarios, significantly simplifying the ...

Joint source-channel LZ'77 coding
Data Compression Conference, 2003. Proceedings. DCC 2003, 2003Limited memory and bounded communication resources require powerful data compression techniques, but at the same time noisy tetherless channels and/or corrupted file systems need error correction capabilities. Joint source-channel coding has emerged as a viable solution to this problem.

Joint Source-Channel Coding Using Variable-Length Codes
Problems of Information Transmission, 2001The paper presents a decoding algorithm for joint source-channel coding when variable-length codes are used for information transmission over a discrete memoryless channel. The asymptotic lower bound on the exponent of the decoding error probability for variable-length codes has been established.

Joint source-channel iterative decoding of codes
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004In this paper an innovative joint source channel coding scheme is presented. The system is based on iterative soft decoding of arithmetic codes, by means of a novel soft-in soft-out decoder based on suboptimal search and pruning of a binary tree. An error resilient arithmetic coder with a forbidden symbol is used in order to improve the performance of ...
