Abstract :
Fountain codes are a class of recently proposed efficient erasure error-control codes. However, the original design of fountain codes, despite being highly efficient for erasure channels, has very poor progressive decoding performance. The purpose of this paper is to design and optimize unequal error protection (UEP) fountain codes to maximize the throughput of multimedia communication systems while providing different levels of guaranteed QoS for heterogenous users. A random interleaved rateless code design is proposed to solve the formulated constraint optimization problem. Numerical results demonstrate the advantage of the proposed design with optimal parameters compared to existing UEP designs.
