Spatially-Coupled MacKay-Neal Codes Universally Achieve the Symmetric Information Rate of Arbitrary Generalized Erasure Channels with Memory
Masaru Fukushima, Takuya Okazaki, Kenta Kasai
This paper investigates the belief propagation decoding of spatially-coupled MacKay-Neal (SC-MN) codes over erasure channels with memory. We show that SC-MN codes with bounded degr…
Non-Binary LDPC Codes with Large Alphabet Size
Koji Tazoe, Kenta Kasai, Kohichi Sakaniwa
We study LDPC codes for the channel with input and output . The aim of this paper is to evaluate decoding performance of $q^m…
Spatially-Coupled MacKay-Neal Codes with No Bit Nodes of Degree Two Achieve the Capacity of BEC
Takuya Okazaki, Kenta Kasai
Obata et al. proved that spatially-coupled (SC) MacKay-Neal (MN) codes achieve the capacity of BEC. However, the SC-MN codes codes have many variable nodes of degree two and have h…
Spatially-Coupled Precoded Rateless Codes with Bounded Degree Achieve the Capacity of BEC under BP decoding
Kosuke Sakata, Kenta Kasai, Kohichi Sakaniwa
Raptor codes are known as precoded rateless codes that achieve the capacity of BEC. However the maximum degree of Raptor codes needs to be unbounded to achieve the capacity. In thi…
Iterative pre-distortion of the non-linear satellite channel
Thibault Deleu, Mathieu Dervin, Kenta Kasai +1
Digital Video Broadcasting - Satellite - Second Generation (DVB-S2) is the current European standard for satellite broadcast and broadband communications. It relies on high order m…
Weight Distribution for Non-binary Cluster LDPC Code Ensemble
Takayuki Nozaki, Masaki Maehara, Kenta Kasai +1
In this paper, we derive the average weight distributions for the irregular non-binary cluster low-density parity-check (LDPC) code ensembles. Moreover, we give the exponential gro…
