Simple Low-Rate Non-Binary LDPC Coding for Relay Channels
Puripong Suthisopapan, Kenta Kasai, Anupap Meesomboon +2
Binary LDPC coded relay systems have been well studied previously with the assumption of infinite codeword length. In this paper, we deal with non-binary LDPC codes which can outpe…
Threshold Improvement of Low-Density Lattice Codes via Spatial Coupling
Hironori Uchikawa, Brian M. Kurkoski, Kenta Kasai +1
Spatially-coupled low-density lattice codes (LDLC) are constructed using protographs. Using Monte Carlo density evolution using single-Gaussian messages, we observe that the thresh…
Analysis of Error Floors of Non-Binary LDPC Codes over MBIOS Channel
Takayuki Nozaki, Kenta Kasai, Kohichi Sakaniwa
In this paper, we investigate the error floors of non-binary low-density parity-check (LDPC) codes transmitted over the memoryless binary-input output-symmetric (MBIOS) channels. W…
Spatially Coupled Quasi-Cyclic Quantum LDPC Codes
Manabu Hagiwara, Kenta Kasai, Hideki Imai +1
We face the following dilemma for designing low-density parity-check codes (LDPC) for quantum error correction. 1) The row weights of parity-check should be large: The minimum dist…
Spatially Coupled Codes over the Multiple Access Channel
Shrinivas Kudekar, Kenta Kasai
We consider spatially coupled code ensembles over a multiple access channel. Convolutional LDPC ensembles are one instance of spatially coupled codes. It was shown recently that, f…
Threshold Saturation on Channels with Memory via Spatial Coupling
Shrinivas Kudekar, Kenta Kasai
We consider spatially coupled code ensembles. A particular instance are convolutional LDPC ensembles. It was recently shown that, for transmission over the memoryless binary erasur…
