Abstract
In this letter, we propose a new cross-level decoding method for LT codes, where the results of packet-level decoding are fed back to bit-level decoding to improve the overall decoding performance. Another advantage of our method is that it keeps the original LT decoder structure and does not require extra real field computation. We provide the revised And-Or Tree analysis for the proposed method and validate it with numerical simulations.
