Logistics‐Grade UHF RFID Tag Design via Surrogate‐Guided Bayesian Optimisation

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
This study presents a highly data‐efficient, surrogate‐guided Bayesian optimisation pipeline (DOE → DNN → BO) to design logistics‐grade Ultra‐High Frequency Radio‐Frequency Identification (UHF RFID) tags. By actively embedding strict European Telecommunications Standards Institute (ETSI) regulatory corridor constraints into the acquisition loop, the ...

Turbo-per-Tone Equalization for ADSL Systems

EURASIP Journal on Advances in Signal Processing, 2005
We study the equalization procedure in discrete multitone (DMT)-based systems, in particular, in DMT-based ADSL systems. Traditionally, equalization is performed in the time domain by means of a channel shortening filter.

Weighted Multi-Band Turbo-Coded FSK for Reliable Underwater Communications

Applied Sciences, 2022
Multi-band communication technology allocates the same data to different frequency bands, improving both performance and propagation efficiency. However, since the performance loss in a particular band affects the entire band, the multi-band structure ...

Thermohydrodynamic Modeling of Two Axial Groove Journal Bearings Under Different Lubrication Conditions

International Journal of Rotating Machinery, Volume 2026, Issue 1, 2026.
Cylindrical hydrodynamic bearings are essential components of rotating machines used in applications ranging from small motors to large turbo generators. They operate based on the principle of a thin oil film that separates the rotating shaft from the bearing, preventing mechanical contact between the surfaces.

Pilot‐Based Iterative Path Estimation and Maximum Ratio Combining (MRC)–Based Signal Detection of Orthogonal Time–Frequency Space (OTFS) Modulation for 6G in Fractional Doppler Channels

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...

EXIT Chart Analysis of Expectation Propagation-Based Iterative Detection and Decoding

IEEE Open Journal of the Communications Society
This paper proposes a novel framework for extrinsic information transfer (EXIT) chart analysis to examine the convergence behavior of iterative detection and decoding (IDD) algorithms based on expectation propagation (EP), specifically addressing the ...

Performance Analysis and Improvement for VAMP Soft Frequency-Domain Equalizers

IEEE Access, 2019
The vector approximate message passing (VAMP) soft frequency-domain equalizer (SFDE) has been proposed for turbo equalization. It consists of an inner soft equalizer (ISE) and an inner soft slicer (ISS), which iteratively exchange block-wise extrinsic ...
