Railway wireless communications play an increasingly significant role in train control and
signal transmission. Communication-based train control system (CBTC) can improve the …

This letter proposes a high-accuracy deep back-projection CNN (DBPCNN)-based
propagation model for radio wave prediction in long guiding structures such as tunnels. The …

Parabolic equation (PE) methods have been widely utilized for modeling radio wave
propagation in tunnels due to their notable efficiency and fidelity. However, as emerging …

One of the major challenges in designing a wireless indoor–outdoor communication network
operating in tunnels and long corridors is to identify the optimal location of the outside …

We present a numerical platform for 3D imaging and general analysis of multidimensional
complex THz fields. A special 3D visualization is obtained by converting electromagnetic …

Radio wave propagation modelling in railway environments is of fundamental importance in
designing reliable train communication systems. Parabolic equation (PE) methods have …

The 60 GHz band has been selected for short-range communication systems to meet
consumers' needs for high data rates. However, this frequency is attenuated by obstacles …

The tunnel is one of the most important scenarios for high-speed railway (HSR). However, it
exists many gaps about the coverage, the path loss and the number of signal paths in the …

In this study, we explore the potential of integrating blockchain technology and cryptographic
primitives such as Schnorr signatures and Pedersen commitments, via a Stamp and Extend …

Monitoring, control and management of wine production using sensors, IoT and machine
learning methods is becoming more and more common. Wireless connection of sensors …
