Influence of Noise-Limited Censored Path Loss on Model Fitting and Path Loss-Based Positioning [PDF]

open access: yesSensors, 2021
Positioning is considered one of the key features in various novel industry verticals in future radio systems. Since path loss (PL) or received signal strength-based measurements are widely available in the majority of wireless standards, PL-based ...

A Simple Analytical Model for THz Band Path Loss

open access: yesIEEE Communications Letters, 2023
In this letter, we devise a frequency, distance, and altitude-dependent, analytical model for THz band path loss. This model is obtained from cascaded regression of transmittance data from Line-by-Line Radiative Transfer Model (LBLRTM) propagation analysis tool, considering altitudes from the sea-level to 1 km, distances from 1 m to 100 m and ...

Path Loss Prediction Model Development in a Mountainous Forest Environment

open access: yesIEEE Open Journal of the Communications Society, 2021
We consider a method for developing a radio-wave propagation prediction model in a mountainous forested area. A new path loss development approach uses a free-space path loss (FSPL) model and an empirical path loss model.

An Enhanced Path Loss Model for Maritime Communication Channels

open access: yesIEEE Access
This study proposes a new ocean propagation loss model, the curved ground loss (CGL) model, to improve the existing models by considering the effects of sea surface roughness, earth curvature, and sea wave height on signal fading at the reflection point.

Selection and Tuning Propagation Path Loss Model for Hawassa City, Ethiopia at 1800 MHz Frequency [PDF]

open access: yesJournal of Applied Research in Electrical Engineering, 2023
Path loss models estimate the average path loss a signal experiences at a particular distance from a transmitter. However, each type of existing path loss propagation model is designed to predict path loss in a particular environment that may be ...

FSO Path Loss Model Based on the Visibility

open access: yesIEEE Photonics Journal, 2022
Free-space optics (FSO) is attracting renewed attention in the frame of 5G, which demands wireless backhauling technologies with extremely high data rates over distances up to a few kilometers. Link availability is a FSO well-known issue due to the large
