Fountain codes are erasure correcting codes realizing reliable communication systems for the multicast in the Internet.
The zigzag decodable fountain (ZDF) code is one of generalization of the Raptor code, i.e., applying shift operation to generate the output packets.
The ZDF code is decoded by a two-stage iterative decoding algorithm, which combines the packet-wise peeling algorithm and the bit-wise peeling algorithm.
By the bit-wise peeling algorithm, ZDF codes outperform Raptor codes under iterative decoding in terms of decoding erasure rate and overhead.
However, the bit-wise peeling algorithm spends long decoding time.
This report proposes a fast bit-wise decoding algorithm for the ZDF codes.
The main idea of the proposed algorithm is to construct a list which records the edges contributing to decoding.
The numerical experiments show that the proposed decoding algorithm reduces decoding time. |
