Rate Distortion Performance for Joint Source Channel ...
This paper presents the rate distortion behavior of Joint Source Channel Coding(JSCC) scheme for still image transmission. The focus is on DCT based sourcecoding JPEG, Rate Compatible Punctured Convolution Codes (RCPC) fortransmission over Additive White Gaussian Noise (AWGN) channel under theconstraint of fixed transmission bandwidth....

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 ......
Rate-Distortion Performance for Joint Source and Channel ...
in image coding [9] and have demonstrated superior performance, both subjectively and objectively and for both low and high degrees of compression, we will combine this technique with two different scalar quantization schemes to build a base for optimizing the rate-distortion behavior of the joint source and channel coders....
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.
 A JOINT SOURCE-CHANNEL DISTORTION MODEL FOR JPEG ...
joint source-channel coding schemes is a distortion model to mea-sure the quality of compressed digital multimedia such as images and videos. Unfortunately, models for estimating the distortion due to quantization and channel bit errors in a combined fashion do not appear to be available for practical image or video coding standards....

Joint Source-Channel Coding, Distortion Model, JPEG, Unequal Power Allocation. I. INTRODUCTION With the introduction of real-time imaging in third generation wireless systems, it is clear that high bandwidth multimedia will be one of the main applications in next generation wireless systems. These
Analog joint source-channel coding over MIMO channels ...
Analog joint source-channel coding (JSCC) is a communication strategy that does not follow the separation principle of conventional digital systems but has been shown to approach the optimal distortion-cost tradeoff over additive white Gaussian noise channels. In this work, we investigate the feasibility of analog JSCC over multiple-input multiple-output (MIMO) fading channels....
JOINT SOURCE/CHANNEL CODING FOR MULTIPLE SOURCES TRANSMISSION
However, these schemes do not take channel coding into account. In [1], a practical joint source/channel coding algorithm based on scalable source coders was proposed for the transmission of multiple images sharing a common channel. It effectively minimizes the expected distortion over all reconstructed images at the receiver end within a given...
