Lossy joint source-channel coding in the finite blocklength regime [PDF]
, 2012 This paper finds new tight finite-blocklength bounds for the best achievable lossy joint source-channel code rate, and demonstrates that joint source-channel code design brings considerable performance advantage over a separate one in the non-asymptotic ...

LDGM Codes for Channel Coding and Joint Source-Channel Coding of Correlated Sources
EURASIP 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 the Performance of Lossless Joint Source-Channel Coding Based on Linear Codes
, 2006 A general lossless joint source-channel coding scheme based on linear codes is proposed and then analyzed in this paper. It is shown that a linear code with good joint spectrum can be used to establish limit-approaching joint source-channel coding ...
