Abstract
A syndrome-based error resilient scheme of distributed joint source-channel coding was addressed. Without increasing the complexity of the encoder, a new appropriate syndrome based encoder with compression and error resilient capability were designed. Secondly, a corresponding decoder was designed and the existing joint decoding algorithm was improved, introducing a new information exchange, to improve the performance of the decoder. Simulation results show that the performance of the proposed scheme is better than that of the existing syndrome-based distributed joint source-channel coding scheme in the noisy channel and the performance of the scheme is also better than that of the parity-based distributed joint source-channel coding when the signal to noise ratio (SNR) is high.
