On the complexity of bandwidth allocation in radio networks

open access: yesTheoretical Computer Science, 2008
AbstractWe define and study an optimization problem that is motivated by bandwidth allocation in radio networks. Because radio transmissions are subject to interference constraints in radio networks, physical space is a common resource that the nodes have to share in such a way, that concurrent transmissions do not interfere.

Online bandwidth auctions for efficient allocation of bandwidth

open access: yesProceedings. 2004 12th IEEE International Conference on Networks (ICON 2004) (IEEE Cat. No.04EX955), 2005
This paper describes an on-line auction process for dynamic bandwidth allocation in communication networks. The auction is intended to be repeated at short (perhaps ten minute) intervals. The outcome of the auction gives both the bandwidth allocation, and the price to be paid for it.

Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView., 2023
The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.
