Low-Complexity Coverage Analysis of Downlink Cellular Network for Combined LOS and NLOS Propagation

Abstract

Recent works on coverage analysis distinguish between the line-of-sight (LOS) and non-LOS links, as they have a significant channel-gain difference. However, analyzing the effect of complex wireless channels while distinguishing between them requires highly complex computation. Herein, we propose an interference approximation method to reduce the computational complexity of such analysis comparing with previously proposed ones. Furthermore, this proposal enables coverage analysis with an only one-fold integral exprescsion while ensuring accurate analysis for various blockage models and parameters, which is validated through simulation.
