A Structured LDPC Code Construction for Efficient Encoder Design

Low-Density Parity Check codes have been widely investigated over the past few years, and construction of Low-Density Parity Check code enabling efficient implementation design represents one of the main topics of interest. This article proposes a new code family, based on a structures code construction with an inherent parallelism. This construction divides the parity check matrix into layers which can be processed simultaneously, improving encoding throughput and latency. Possible optimizations and example are proposed and illustrated.
