Abstract (in Japanese) (See Japanese page) 
(in English) Fountain codes are erasure correcting codes realizing the reliable communication for the multicast in the Internet. Zigzag decodable fountain (ZDF) codes have good decoding performance with the decoder combined the peeling algorithm with the zigzag decoding (ZD) algorithm. However, the number of iterations of the decoder is greater than the decoder for the Raptor codes. The tree-structure expectation propagation (TEP) is a decoding algorithm for the low-density parity-check codes over the binary erasure channels and an extension of peeling algorithm. In this paper, we extend the TEP for the ZDF codes and propose a decoding algorithm combined the TEP with the ZD algorithm. Simulation results show that the proposed decoding algorithm reduces the number of decoding iterations as compared with the previous decoding algorithm. Moreover, simulation results show that the proposed decoding algorithm has the same decoding performance as the previous decoding algorithm.
