Mitigation of Packet Erasure using New Fountain Code Design

摘要

Fountain codes witnessed great attention since the earlier attempts of J. W. Byers and his colleagues. These codes performed with high efficiency in the erasure channels where the packet lost problem exist. The construction of the coded symbols is mainly influenced by the design of the degree generation which on the other hand plays a significant role in recovering of the information packets. In this paper, a new fountain code based on Luby transform (LT) code patterns is presented with fixed degree frame and cyclic data selection (FDCD). The simulation results compare our proposed degree generation with other conventional degree distributions. These results show better performance with respect to packet recovery abilities.
