Two-stage Beamformer Design via Deterministic Equivalents
Hossein Asgharimoghaddam, Antti Tölli
Complexity reduction of optimal linear receiver is considered in a scenario where both the number of single-antenna user equipments (UEs) and base station (BS) antennas are…
Capacity Approaching Low Density Spreading in Uplink NOMA via Asymptotic Analysis
Hossein Asgharimoghaddam, Jarkko Kaleva, Antti Tölli
Low-density spreading non-orthogonal multiple-access (LDS-NOMA) is considered where single-antenna user-equipments (UEs) communicate with a base-station (BS) over fading su…
Contextual Bandit Learning for Machine Type Communications in the Null Space of Multi-Antenna Systems
Samad Ali, Hossein Asgharimoghaddam, Nandana Rajatheva +2
In this paper, a novel approach based on the concept of opportunistic spatial orthogonalization (OSO) is proposed for interference management between machine type communications (M…
Decentralizing Multicell Beamforming via Deterministic Equivalents
Hossein Asgharimoghaddam, Antti Tölli, Luca Sanguinetti +1
This paper focuses on developing a decentralized framework for coordinated minimum power beamforming wherein base stations (BSs), each equipped with antennas, serve sin…
