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.

Space-Time Physical-Layer Network Coding

Due to the superposition and broadcast nature of the wireless medium, unmanaged interference results in diminishing data rates in wireless networks. With a recently developed network coding strategy, however, it was demonstrated that interference is no longer adverse in communication networks, provided that it can sagaciously be harnessed. This approach of exploiting interference has opened the possibility of better performance in the interference-limited communication regime than traditionally thought possible.
