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 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…
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…
Efficient Termination of Spatially-Coupled Codes
Koji Tazoe, Kenta Kasai, Kohichi Sakaniwa
Spatially-coupled low-density parity-check codes attract much attention due to their capacity-achieving performance and a memory-efficient sliding-window decoding algorithm. On the…
Spatially-Coupled Precoded Rateless Codes
Kosuke Sakata, Kenta Kasai, Kohichi Sakaniwa
Raptor codes are rateless codes that achieve the capacity on the binary erasure channels. However the maximum degree of optimal output degree distribution is unbounded. This leads…
Spatially-Coupled Binary MacKay-Neal Codes for Channels with Non-Binary Inputs and Affine Subspace Outputs
Kenta Kasai, Takayuki Nozaki, Kohichi Sakaniwa
We study LDPC codes for the channel with -ary input and output . The receiver kn…
