Analytical Solution of Covariance Evolution for Irregular LDPC Codes
Takayuki Nozaki, Kenta Kasai, Kohichi Sakaniwa
A scaling law developed by Amraoui et al. is a powerful technique to estimate the block error probability of finite length low-density parity-check (LDPC) codes. Solving a system o…
Effects of Single-Cycle Structure on Iterative Decoding for Low-Density Parity-Check Codes
Ryuhei Mori, Toshiyuki Tanaka, Kenta Kasai +1
We consider communication over the binary erasure channel (BEC) using low-density parity-check (LDPC) codes and belief propagation (BP) decoding. For fixed numbers of BP iterations…
Design and Performance of Rate-compatible Non-Binary LDPC Convolutional Codes
Hironori Uchikawa, Kenta Kasai, Kohichi Sakaniwa
In this paper, we present a construction method of non-binary low-density parity-check (LDPC) convolutional codes. Our construction method is an extension of Felstroem and Zigangir…
Weight Distributions of Multi-Edge type LDPC Codes
Kenta KASAI, Tomoharu AWANO, David DECLERCQ +2
The multi-edge type LDPC codes, introduced by Richardson and Urbanke, present the general class of structured LDPC codes. In this paper, we derive the average weight distributions…
Fourier Domain Decoding Algorithm of Non-Binary LDPC codes for Parallel Implementation
Kenta Kasai, Kohichi Sakaniwa
For decoding non-binary low-density parity check (LDPC) codes, logarithm-domain sum-product (Log-SP) algorithms were proposed for reducing quantization effects of SP algorithm in c…
Fountain Codes with Multiplicatively Repeated Non-Binary LDPC Codes
Kenta Kasai, Kohichi Sakaniwa
We study fountain codes transmitted over the binary-input symmetric-output channel. For channels with small capacity, receivers needs to collects many channel outputs to recover in…
