Abstract
In this paper, we propose an efficient soft iterative decoding method for raptor codes, which are customized for satellite broadcasting systems. The raptor codes presented in this paper are composed of a systematic LDPC code concatenated with another systematic Luby transform (LT) code. The outer codes are DVB-S2 and DVB-S2X defined forward error correction codes for interactive satellite broadcasting systems. For efficient soft decoding of the raptor codes, we represent both of the component codes with the same graph structure. Based on the Tanner graph drawn in terms of bit nodes and check nodes for each component code, we present an efficient joint iterative soft decoding method with a parallel process.
