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

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 ......

configuration is then derived. After that, a joint source-channel coding (JSCC) problem is formulated to find the optimal numbe r of JPEG 2000 quality layers for the image and the number of channel coding packets for each JPEG 2000 codeblock that can minimize the reconstructed image distortion for the two users, subject to a rate constraint....
