Volume of Metric Balls in High-Dimensional Complex Grassmann Manifolds
Renaud-Alexandre Pitaval, Lu Wei, Olav Tirkkonen +1
Volume of metric balls relates to rate-distortion theory and packing bounds on codes. In this paper, the volume of balls in complex Grassmann manifolds is evaluated for an arbitrar…
From Random Matrix Theory to Coding Theory: Volume of a Metric Ball in Unitary Group
Lu Wei, Renaud-Alexandre Pitaval, Jukka Corander +1
Volume estimates of metric balls in manifolds find diverse applications in information and coding theory. In this paper, some new results for the volume of a metric ball in unitary…
Coordination protocol for inter-operator spectrum sharing based on spectrum usage favors
Bikramjit Singh, Konstantinos Koufos, Olav Tirkkonen
Currently, mobile network operators are allocated spectrum bands on an exclusive basis. While this approach facilitates interference control, it may also result in low spectrum uti…
Coordination protocol for inter-operator spectrum sharing in co-primary 5G small cell networks
Bikramjit Singh, Sofonias Hailu, Konstantinos Koufos +4
We consider spectrum sharing between a limited set of operators having similar rights for accessing spectrum. A coordination protocol acting on the level of the Radio Access Networ…
Co-primary inter-operator spectrum sharing over a limited spectrum pool using repeated games
Bikramjit Singh, Konstantinos Koufos, Olav Tirkkonen +1
We consider two small cell operators deployed in the same geographical area, sharing spectrum resources from a common pool. A method is investigated to coordinate the utilization o…
A Low-Complexity Message Recovery Method for Compute-and-Forward Relaying
Amaro Barreal, Joonas Pääkkönen, David Karpuk +2
The Compute-and-Forward relaying strategy achieves high computation rates by decoding linear combinations of transmitted messages at intermediate relays. However, if the involved r…
