Computationally Efficient Estimation of the Spectral Gap of a Markov Chain
Richard Combes, Mikael Touati
We consider the problem of estimating from sample paths the absolute spectral gap of a reversible, irreducible and aperiodic Markov chain over a fi…
Hierarchical Beamforming: Resource Allocation, Fairness and Flow Level Performance
Julien Floquet, Richard Combes, Zwi Altman
We consider hierarchical beamforming in wireless networks. For a given population of flows, we propose computationally efficient algorithms for fair rate allocation including propo…
Device-to-Device Aided Multicasting
Thomas Varela Santana, Richard Combes, Mari Kobayashi
We consider a device-to-device (D2D) aided multicast channel, where a transmitter wishes to convey a common message to many receivers and these receivers cooperate with each other.…
Utility Optimal Scheduling for Coded Caching in General Topologies
Richard Combes, Asma Ghorbel, Mari Kobayashi +1
We consider coded caching over the fading broadcast channel, where the users, equipped with a memory of finite size, experience asymmetric fading statistics. It is known that a nai…
