Structured Hypergraphs in Cellular Mobile Communication Systems

open access: yesProceedings of the 24th International Conference on Distributed Computing and Networking, 2022
An open problem is to extend the results in the literature on unit disk graphs to  hypergraph models.  Motivated by recent results that the worst-case performance of the distributed maximal scheduling algorithm is characterized by the interference degree of the hypergraph, in the present work we investigate properties of the interference degree of the ...

Hypergraph models for cellular mobile communication systems

open access: yesIEEE Transactions on Vehicular Technology, 1998
Cellular systems have hitherto been modeled mostly by graphs for the purpose of channel assignment. However, hypergraph modeling of cellular systems offers a significant advantage over graph modeling in terms of the total traffic carried by the system.

Downlink beamforming for cellular mobile communications [PDF]

open access: yes1997 IEEE 47th Vehicular Technology Conference. Technology in Motion, 2002
A new technique for downlink transmission beamformer design in cellular mobile communications systems using an antenna array at the base station is presented. The method is based on estimation of an underlying spatial distribution associated with each source's spatial downlink channel.
