Erasure Floor Analysis of Distributed LT Codes

Abstract: We investigate the erasure floor performance of distributed Luby transform (DLT) codes for transmission within a multi-source, single-relay, and single-destination erasure-link network. In general, Luby transform (LT) codes exhibit a high erasure floor due to poor minimum-distance properties, which can be improved by maximizing the minimum variable-node degree. The same behavior is observed for DLT codes, and therefore a new combining scheme at the relay is proposed to maximize the minimum variable-node degree… Show more

“…And to maximize the minimum-distance of variable-node degree, [13] proposed the Rescheduled distributed LT Codes, which can abate the error floor remarkably. [14] proposed a Hybrid Soliton Distribution Coding which engage the Robust Soliton Distribution (RSD) and the deconvolved Robust Soliton Distribution (DSD) [6], but it can only deal with the 2n-sources networks.…”
