A unary error correction code for the near-capacity joint source and channel coding of symbol values from an infinite set [PDF]
, 2013 A novel Joint Source and Channel Code (JSCC) is proposed, which we refer to as the Unary Error Correction (UEC) code. Unlike existing JSCCs, our UEC facilitates the practical encoding of symbol values that are selected from a set having an infinite ...

Joint source-channel coding with inner irregular codes [PDF]
2008 IEEE International Symposium on Information Theory, 2008 We address the optimization of joint source-channel coding schemes for iterative source-channel decoding of first- order Markov sources. Compared to the traditional design, we propose two novelties: (1) source encoders, providing code words with a minimum Hamming distance dminges2, realized by linear block codes, and (2) irregular channel encoders ...

Joint Source-Channel Polarization With Side Information
IEEE Access, 2018 As an extension of source polarization and channel polarization, this paper considers joint source-channel polarization, which results in a joint source-channel coding (JSCC) scheme using a quasiuniform systematic polar code (SPC).

Serially Concatenated Joint Source-Channel Coding for Binary Markov Sources [PDF]
, 2011 In this paper, we propose a joint design of serially concatenated source channel coding for binary Markov sources over AWGN channels. To exploit the memory structure inherent within the sequence output from the source, modifications are made on the BCJR ...

A survey on deep learning based joint source-channel coding
Dianxin kexue, 2020 Classical information theory shows that separate source-channel coding is asymptotically optimal over a point-to-point channel.As modern communication systems are becoming more sensitive to delays and bandwidth,it becomes difficult to adopt the ...

On practical design for joint distributed source and network coding [PDF]
, 2009 This paper considers the problem of communicating correlated information from multiple source nodes over a network of noiseless channels to multiple destination nodes, where each destination node wants to recover all sources. The problem involves a joint

EURASIP Journal on Image and Video Processing, 2007 An efficient approach for joint source and channel coding is presented. The proposed approach exploits the joint optimization of a wavelet-based scalable video coding framework and a forward error correction method based on turbo codes.

Two-Dimensional Iterative Source-Channel Decoding for Distributed Video Coding [PDF]
, 2014 Motivated by the Joint Source-Channel Decoding (JSCD) principle of exploiting the source redundancy, in this treatise we study the application of iterative source-channel decoding (ISCD) conceived for distributed video coding (DVC), where the video ...

Distributed joint source-channel arithmetic coding [PDF]
2010 IEEE International Conference on Image Processing, 2010 We address distributed source coding with decoder side information, when the decoder observes the source through a noisy channel. Existing approaches employ syndromeor parity-based channel codes. We propose a new approach based on distributed arithmetic coding (DAC).We introduce a DAC with forbidden symbol, which allows to tune the redundancy according

Joint Network/Channel Coding for Multi-User Hybrid-ARQ
, 2008 We present a novel multi-user hybrid-ARQ scheme for a wireless multiple-unicast scenario where a base station supplies a group of users with individual messages.
