Over the last decade, railway industry has seen a huge transition from conventional railway
signalling systems to modern, communication-based signalling systems. Communications …

In this paper, an optimal model is developed for path loss predictions using the Feed-
Forward Neural Network (FFNN) algorithm. Drive test measurements were carried out in …

Path loss models are essential in the planning of wireless networks. However, the peculiar
ambient characteristics of geographical locations necessitate a wide range of these models …

Terrestrial signal loss prediction for the VHF band is limited to a few models. With perpetual
prominence in its application, understanding VHF signal variation in a different scenario …

This paper presents five commonly used radio propagation models (RPMs) which are
suitable for the prediction of path loss in macrocell environments of LTE wireless …

When designing and maintaining a wireless network, engineers need to first evaluate the
impact of a specific propagation environment on radio wave propagation. Currently …

In this paper, radio propagation predictions were performed by a self‐developed ray tracing
simulator based on highly accurate three‐dimensional (3D) environment models obtained …

The aim of this paper was to propose quantitative measurement of path loss model
adaptation in urban radio propagation for a second‐generation, terrestrial digital video …

For the 5G‐R wireless communication system of the next‐generation high‐speed railway,
there is a problem of single algorithm consideration when handover is carried out. In high …

This paper presents the evaluation results of the radio signal propagation prediction using
Longley-Rice model in railways installed in rural areas with significant variation of …
