Fading Characteristics of Wireless Channel on High-Speed Railway in Hilly Terrain Scenario

International Journal of Antennas and Propagation, 2013
This paper focuses on the fading characteristics of wireless channel on High-Speed Railway (HSR) in hilly terrain scenario. Due to the rapid speed, the fading characteristics of HSR channel are highly correlated with time or Transmit-Receive distance and

Parameter Identification of PMSM with Finite-difference-based Strong Tracking H∞ Filter

Journal of Harbin University of Science and Technology
The tracking maneuver process accuracy of traditional H∞ filter is not enough for high precision control fields. A finite difference-based strong tracking H∞ filter (FD-STHF) is proposed for permanent magnet synchronous motor ( PMSM), which can improve ...

Performance Analysis of Dense Small Cell Networks With Practical Antenna Heights Under Rician Fading

IEEE Access, 2018
In this paper, we examine the combined impacts of distance-dependent Rician fading channel model and the absolute difference between the heights of base station (BS) and user equipment (UE) antennas on the coverage probability and the area spectral ...

A Novel Adaptive Factor-Based H∞ Cubature Kalman Filter for Autonomous Underwater Vehicle

Journal of Marine Science and Engineering, 2022
In the navigation of an autonomous underwater vehicle (AUV), the positioning accuracy and stability of the navigation system will decrease due to uncertainties such as mobility, inaccuracy of a priori process noise characteristic, and simplification of a

Wireless Link Capacity under Shadowing and Fading

, 2017
We consider the following basic link capacity (a.k.a., one-shot scheduling) problem in wireless networks: Given a set of communication links, find a maximum subset of links that can successfully transmit simultaneously.

The onset of photoionization in Sakurai's Object (V4334 Sgr) [PDF]

, 2007
We investigate the reheating of the very late thermal pulse (VLTP) object V4334 Sgr (Sakurai's Object) using radio observations from the Very Large Array, and optical spectra obtained with the Very Large Telescope. We find a sudden rise of the radio flux

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

Exact ZF Analysis and Computer-Algebra-Aided Evaluation in Rank-1 LoS Rician Fading [PDF]

, 2016
We study zero-forcing detection (ZF) for multiple-input/multiple-output (MIMO) spatial multiplexing under transmit-correlated Rician fading for an N_R X N_T channel matrix with rank-1 line-of-sight (LoS) component.
