Interleaver Design for Small-Coupling-Length Spatially Coupled Protograph LDPC-Coded BICM Systems Over Wireless Fading Channels

IEEE Access, 2020
As a class of convolutional error-correction codes (ECCs), spatially coupled protograph low-density parity-check (SC-PLDPC) codes with a sufficiently large coupling length can approach the channel capacity under belief propagation (BP) decoding. However,

Adaptive RAC codes employing statistical channel evaluation [PDF]

, 2016
In time varying channels the noise and interference vary randomly. Forward error correction codes (FEC) on  such channels are designed to cater for the worst possible state and require a large amount of redundancy at  all time.

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

International Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

The multifactorial aquaculture‐related COVID‐19 shock in Benin, West Africa: A socio‐economic perspective of mitigating the disruptive impacts on the small‐scale and subsistence producers

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 507-521, December 2022., 2022
Graphical Abstract This study deals with a timely topic, COVID‐19, whose impacts on aquaculture have never been quantified in Benin. Direct discussions were held with aquaculture producers to understand how they are feeling the impact of the pandemic on their business.

Species identification in fish meal from urban fisheries biomass with DNA metabarcoding analysis

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 562-571, December 2022., 2022
Fish species constructing fish meal (FM) made from urban fisheries biomass, which is fisheries by‐products collected downstream in the seafood supply chain were detected with a DNA metabarcoding method. 81–122 species were detected in the FM, and fish species indicated as Critically Endangered (CR) or Endangered (EN) on the International Union for ...

Efficient T-EMS Based Decoding Algorithms for High-Order LDPC Codes

IEEE Access, 2019
Non-binary low-density parity-check (NB-LDPC) codes show larger coding gain and lower error floor than their binary counterparts in many cases. However, the existing soft decoding algorithms of NB-LDPC codes generally suffer from high computational ...
