Operational rate-distortion performance for joint source and channel coding of images Abstract: This paper describes a methodology for evaluating the operational rate-distortion behavior of combined source and channel coding schemes with particular application to images....
Joint Source-Channel Coding for JPEG Compressed Images ...
In this paper, we develop an approach toward joint source-channel coding (JSCC) for JPEG compressed image transmission. First, a data partition (DP) technique is employed to divide the JPEG bitstream into three groups, namely, Huffman codes, DC coefficients and AC coefficients. Second, we combine the rate-compatible punctured convolutional (RCPC) codes to protect the coded data according to ......
Robust transform image coder over noisy channel | Request PDF
A combined source-channel coding approach is described for the encoding, transmission, and remote reconstruction of image data. Several two dimensional image source encoding schemes are considered.

the source coding distortion and channel-coding distortion as and , respectively. If we assume that and are uncorrelated (which is usually true, see [9]), we have . The goal of JSCC is to minimize the overall distortion under a given resource (coding bits) constraint, by optimally allocating source coding and channel-coding bits. B. Hash ......
LDPC-based Joint Source Channel Coding and Decoding ...
We define the R s c = l n as the source coding rate, and R c c = l m as the channel coding rate. The overall rate of the system is R = n m. The LDPC-based JSC message-passing decoding is performed on a Tanner graph with the BP algorithm by exchanging extrinsic log-likelihood ratios (LLRs) between the source and the channel LDPC decoders....
