The Restless Hidden Markov Bandit with Linear Rewards and Side Information
Michal Yemini, Amir Leshem, Anelia Somekh-Baruch
In this paper we present a model for the hidden Markovian bandit problem with linear rewards. As opposed to current work on Markovian bandits, we do not assume that the state is kn…
Noisy Beeping Networks
Yagel Ashkenazi, Ran Gelles, Amir Leshem
We introduce noisy beeping networks, where nodes have limited communication capabilities, namely, they can only emit energy or sense the channel for energy. Furthermore, imperfecti…
Eliminating Interference in LOS Massive Multi-User MIMO with a Few Transceivers
Uri Erez, Amir Leshem
Wireless cellular communication networks are bandwidth and interference limited. An important means to overcome these resource limitations is the use of multiple antennas. Base sta…
Distributed Learning for Channel Allocation Over a Shared Spectrum
S. M. Zafaruddin, Ilai Bistritz, Amir Leshem +1
Channel allocation is the task of assigning channels to users such that some objective (e.g., sum-rate) is maximized. In centralized networks such as cellular networks, this task i…
The Interference Channel Revisited: Aligning Interference by Adjusting Receive Antenna Separation
Amir Leshem, Uri Erez
It is shown that a receiver equipped with two antennas may null an arbitrary large number of spatial directions to any desired accuracy, while maintaining the interference-free sig…
