Reduced-complexity syndrome-based TTCM decoding [PDF]

open access: yes, 2013
The iterative decoder of Turbo Trellis Coded Modulation (TTCM) exchanges extrinsic information between the constituent TCM decoders, which imposes a high computational complexity at the receiver. Therefore we conceive the syndrome-based block decoding of

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 ...

Joint semi-blind detection and channel estimation in space-frequency trellis coded MIMO-OFDM [PDF]

open access: yes, 2003
This paper considers an OFDM system with a multiple-input multiple-output (MIMO) configuration, which uses space-frequency trellis coding (SFTC). A novel method of decoding SFTC without a need to transmit separate training sequences is developed.

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.
