Large scale survey for radio propagation in developing machine learning model for path losses in communication systems

open access: yesScientific African, 2023
Several orthodox approaches, such as empirical methods and deterministic methods, had earlier been used for the prediction of path loss in wireless communication systems. These approaches are either inefficient or complex.

Measurement of loss pairs in network paths [PDF]

open access: yesProceedings of the 10th ACM SIGCOMM conference on Internet measurement, 2010
Loss-pair measurement was proposed a decade ago for discovering network path properties, such as a router's buffer size. A packet pair is regarded as a loss pair if exactly one packet is lost. Therefore, the residual packet's delay can be used to infer the lost packet's delay.

Material Characterization and Radio Channel Modeling at D-Band Frequencies

open access: yesIEEE Access, 2021
As the throughput requirements for wireless communication links keep rising, characterization of sub-THz radio channels is necessary. This paper presents the results of a radio channel measurement campaign in which we characterize the full D-band ...

Model for the Path Loss of In-Room Reverberant Channels [PDF]

open access: yes2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011
A general path loss model for in-room radio channels is proposed. The model is based on experimental observations of the behavior of the delay power spectrum in closed rooms. In a given closed room, the early part of the spectrum observed at different positions typically consists of a dominant component (peak) that vanishes as the transmitter-receiver ...

Electromagnetic Insights Into Path Loss Modelling of IRS-Assisted SISO Links: Method-Of-Moment Based Analysis

open access: yesFrontiers in Communications and Networks, 2021
In this paper, we demonstrate the usefulness of MoM (Method-of-Moments) based methods in efficient path-loss modelling for SISO (single-input single-output) communication links assisted by IRS (Intelligent Reflecting Surfaces).

Path loss modelling based on path profile in urban propagation environments [PDF]

open access: yesIET Communications, 2022
Abstract This paper presents a path loss model based on path profile in urban propagation environments for 5G systems. Although deep learning approaches are indeed powerful in tasks involving prediction or classification, they often lack transparency and suffer from high computational complexity.
