A high‐precision timing and frequency synchronization algorithm for multi‐h CPM signals

open access: yesIET Communications, Volume 18, Issue 17, Page 1049-1061, October 2024.
This paper presents an innovative approach for achieving timing and frequency synchronization for multi‐h continuous phase modulation (CPM) signals. To rectify timing offset and mitigate the adverse effects of noise in received signals, a re‐configurable local filter generation method is integrated into the timing synchronization algorithm ...

Hyperspectral and Photodiode Retrievals of Nighttime LED‐Induced Chlorophyll Fluorescence (LEDIF) for Tracking Photosynthetic Phenology in a Vineyard

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 129, Issue 1, January 2024.
Abstract The magnitude of chlorophyll fluorescence emission represents both chlorophyll content and energy quenching processes enabling its application to serve as a proxy of photosynthetic activity. Thus, there is interest in advancing methods for canopy‐scale monitoring of chlorophyll fluorescence.

The Influences of Rootstock on the Performance of Pinot Noir (Vitis vinifera L.): Phenological Progress, Physiological Performance, and Petiole Nutrient Status

open access: yesAustralian Journal of Grape and Wine Research, Volume 2024, Issue 1, 2024.
Background and Aims. Rootstocks are widely utilised in viticulture industry to prevent the infestation of phylloxera, but they may affect the growth and performance of the scion. This project investigated the impacts of 14 different rootstocks on the phenological, physiological, and nutritional performance of the scion using Vitis vinifera L. cv. Pinot

Exploring Interactions Between Vineyard Performance, Grape and Wine Composition and Subregional Boundaries—The Terroir of Barossa Shiraz

open access: yesAustralian Journal of Grape and Wine Research, Volume 2024, Issue 1, 2024.
Background and Aims: Viticulturists and winemakers have a considerable interest in understanding the influence of climate, soil, viticultural and winemaking practices on wine sensory outcomes—that is, understanding the terroir concept, which is important for regionality and claims of product distinctiveness. In this investigation, an empirical study of
