A Joint Source-Channel Video Coding Scheme Based on Distributed Source Coding

IEEE Transactions on Multimedia, 2008
Recently, several error resilient schemes have been proposed to tackle the error propagation problem in the motion-compensated predictive video coding based on a promising technique - distributed source coding (DSC). However, these schemes mainly apply the distributed source codes for channel error correction, while under-utilizing their capability for

Distributed Joint Source-Channel Coding Using Unequal Error Protection LDPC Codes

IEEE Transactions on Communications, 2013
This paper presents a general approach to designing distributed joint source channel (DJSC) codes with arbitrary rates for communication of a pair of correlated binary sources over noisy channels. In this approach, both distributed compression and channel error correction are simultaneously achieved by transmitting, for each source, a fraction of the ...

Symmetric Distributed Joint Source-Channel Coding Using Raptor Codes

2010 IEEE Fifth International Conference on Networking, Architecture, and Storage, 2010
Distributed compression of correlated sources has been discussed much in wireless sensor networks, while the error-resilient implementation of this efficient coding strategy is one of the crucial issues for applications. In this paper, a symmetric Distributed Joint Source-Channel Coding (DJSCC) scheme is proposed by using Raptor codes for the ...

Distributed Joint Source-Channel Coding of Video Using Raptor Codes

Data Compression Conference, 2005
Summary form only given. In this paper, we consider the case of a noisy channel in Wyner-Ziv coding (WZC) and address distributed joint source-channel coding (JSCC), while targeting at video transmission over packet erasure channels. Our idea is to use a single Raptor code, for both SWC and erasure protection.

Distributed joint source-channel coding of video

IEEE International Conference on Image Processing 2005, 2005
Based 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 distributed source-channel coding for 3D videos

SPIE Proceedings, 2011
This paper presents a distributed joint source-channel 3D video coding system. Our aim is the design of an efficient coding scheme for stereoscopic video communication over noisy channels that preserves the perceived visual quality while guaranteeing a low computational complexity.

Joint source-channel coding for distributed sensor networks

Conference Record of the Thirty-Eighth Asilomar Conference on Signals, Systems and Computers, 2004., 2005
In a decentralized detection system, a number of peripheral nodes gather observations from an environment and communicate relevant information to a fusion center for collective decision making. In systems employing tetherless transmission between the sensor nodes and the fusion center, the presence of communication channels need to be taken into ...

Distributed Joint Source-Channel Decoding Using Systematic Polar Codes

IEEE Communications Letters, 2018
This letter proposes a novel joint decoding scheme for correlated sources using systematic polar codes. In the proposed scheme, each source independently encodes its message into a systematic polar code word and sends the codeword via a binary-input additive white Gaussian noise channel to the common destination, where adaptive cyclic redundancy check ...
