Towards a Comprehensive Ray-Tracing Modeling of an Urban City With Open-Trench Drains for Mobile Communications

Autor: Soo Yong Lim, Qi Ping Soo, Ahmed Adam, David Wee Gin Lim, Zhengqing Yun, Magdy F. Iskander

Publikováno v: IEEE Access, Vol 5, Pp 2300-2307 (2017)

This paper investigates the impacts that open-trench drains make on the accuracy of radio propagation prediction in an urban city environment. Compared with conventional prediction styles that assume the ground to be flat, in this paper, we have cons
