During the last decade, extensive research has been carried out on the subject of low-cost sensor platforms for air quality monitoring. A key aspect when deploying such systems is the quality of the measured data. Calibration is especially important

Generalized Very High Throughput Unrolled LDPC Layered Decoder

Autor: Daian Stein, Alexandru Amaricai, Oana Boncalo

Publikováno v: 2020 28th Telecommunications Forum (TELFOR).

Unrolled layered LDPC architectures have been shown to obtain tens of Gbps throughputs. These types of decoders are well suited to array LDPC codes, for which they present improved throughput. In this paper, we propose a generalization for unrolled l

Code-design for efficient pipelined layered LDPC decoders with bank memory organization

Autor: David Declercq, Valentin Savin, Oana Boncalo, Gyorgy Kolumban-Antal

Publikováno v: Microprocessors and Microsystems. 63:216-225

This paper presents an architecture-aware Progressive Edge Growth (PEG)-based construction method for Low-Density Parity-Check (LDPC) codes. We target optimization through code construction for layered architectures with pipelined processing and memo

In this letter, we address the issue of early stopping criterion for layered LDPC decoders, aiming at more safeness with low hardware cost and minimum latency. We introduce a new on-the-fly measure in the decoder, called in-between layers partial syn

International audience; This paper proposes a holistic approach that addresses both the message mapping in memory banks and the pipeline-related data hazards in low-density parity-check (LDPC) decoders. We consider a layered hardware architecture usi
