| Abstract(in English) | Fountain codes realize reliable communication systems for the multicast with user datagram protocol (UDP). The zigzag decodable fountain (ZDF) codes are designed by shift distribution and have small decoding erasure rates. The purpose of this research is to improve the decoding erasure rates of ZDF codes. To achieve this purpose, we propose a detailed design of shift distribution for ZDF code. Moreover, we compare the decoding erasure rates by numerical simulations and analyze the asymptotic decoding erasure rates by the density evolution. As a result, we see that the proposed design lowers the decoding erasure rates in the waterfall region and asymptotic packet overheads. Furthermore, we analyze the decoding erasure rates in the error floor region. |
