PL-GAN: Path Loss Prediction Using Generative Adversarial Networks
IEEE Access, 2022 Accurate prediction of path loss is essential for the design and optimization of wireless communication networks. Existing path loss prediction methods typically suffer from the trade-off between accuracy and computational efficiency. In this paper, we present a deep learning based approach with clear advantages over the existing ones.

Path Loss Model with Multiple-Antenna
The Journal of Korean Institute of Electromagnetic Engineering and Science, 2014 In this paper, we propose a path loss model with the multiple antennas using diversity efiect. Currently wireless communication systems use the multiple antennas in order to improve the channel capacity or diversity gain. However, until recently, many researches on path loss model only consider geographical environment between the transmitter and the ...

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