The recently proposed unary error correction (UEC) and Elias gamma error correction (EGEC) codes facilitate the near-capacity joint source and channel coding (JSCC) of symbol values selected from large alphabets at a low complexity. Despite their large alphabet, these codes were only designed for a limited range of symbol value probability distributions. In this paper, we generalize the family of...
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 independent channels case. The channel noise and the correlation...
In this paper, we consider the problem of distributed joint source and channel coding(DJSCC), which combines distributed source coding and channel coding into one single encoder. Unlike other parity-based DJSCC schemes,we here employ syndrome-based method which has been considered as optimal in compression but loss of error resilience, to achieve the same goal as parity-based method. The proposed...
