Abstrakt

We analyze a class of rateless codes, called Luby transform (LT) codes with unequal error protection (UEP). We show that while these codes successfully provide UEP, there is a significant price in terms of redundancy in the lower prioritized segments. We propose a modification with a single intermediate feedback message. Our analysis shows a dramatic improvement on the decoding performance of the lower prioritized segment.
