Spectral Efficiency of Determinantal Cellular Wireless Networks

Base station point patterns are known to be way better represented by determinantal point processes rather than Poisson point processes. The extension of the Poisson cellular coverage formulas obtained a few years ago by WNCG Profs. Jeffrey Andrews, François Baccelli and collaborator R. Ganti has been a challenge since that time. In a recent paper, WNCG Alumni Y. Li and Harpreet Dhillon, with François Baccelli and Jeffrey Andrews, gave a general answer to this question. In this paper determinantal point processes are demonstrated to be analytically tractable by leveraging several unique computational properties. Specifically, the paper showed that the empty space function, the nearest-neighbor function and the interference Laplace transform have nice integral expressions. This discovery can then be used to derive an integral expression for spectral efficiency in any cellular network where base stations are distributed in a determinantal way.
