Abstract :
Fountain Codes are essentially Forward Error Correction (FEC) codes, which were developed for applications involving multicasting or for delivering large amounts of content to multiple recipients simultaneously. FEC increases the reliability of a system in a noisy environment. Luby Transform codes (LT codes) which come from a new coding family of the Fountain codes are the first realization of rateless codes which can generate potentially limitless code words from data. In this paper, a performance analysis of Fountain codes for erasure channels, which use the Robust Soliton distribution for encoding the data packets and belief propagation to decode the received packets has been carried out Results show that the overhead during decoding is around 11.2%.
