Fountain codes based on zigzag decodable coding.
TL;DR: This paper proposes a fountain code whose space decoding complexity is nearly equal to that for the Raptor codes, and Simulation results show that the proposed fountain coding system outperforms Raptor coding system in terms of the overhead for the received packets.
Journal ArticleDOI
Zigzag Decodable Fountain Codes
TL;DR: This paper proposes a fountain coding system which has lower space decoding complexity and lower decoding erasure rate than the Raptor coding systems, and analyzes the overhead for the received packets, decoding erasures, decoding complexity, and asymptotic overhead of the proposed fountain code.
Journal ArticleDOI
Analytical Solution of Covariance Evolution for Irregular LDPC Codes
TL;DR: This paper presents the analytical solution of the covariance evolution for irregular LDPC code ensembles and its application to block erasure probabilities of finite- length low-density parity-check codes.
Proceedings ArticleDOI
Analysis of Error Floors of Non-Binary LDPC Codes over MBIOS Channel
TL;DR: A necessary and sufficient condition for successful decoding of zigzag cycle codes over the MBIOS channel by the BP decoder is clarified and expurgate non-binary LDPC code ensemble to analyze and to lower the error floor.
