Enhanced Channel Estimation in Massive MIMO via Coordinated Pilot Design [PDF]
arXiv, 2019 Pilot contamination is a limiting factor in multicell massive multiple-input multiple-output (MIMO) systems because it can severely impair channel estimation. Prior works have suggested coordinating pilot design across cells in order to reduce the channel estimation error caused by pilot contamination. In this paper, we propose a method for coordinated

Learning How to Demodulate from Few Pilots via Meta-Learning
, 2019 Consider an Internet-of-Things (IoT) scenario in which devices transmit sporadically using short packets with few pilot symbols. Each device transmits over a fading channel and is characterized by an amplifier with a unique non-linear transfer function ...

Arthritis Care &Research, EarlyView.Objective Despite knowledge that health outcomes vary according to patient characteristics, identity, and geography, including underrepresented populations in arthritis research remains a challenge. We conducted interviews to explore how researchers in arthritis have used equity, diversity, and inclusion (EDI) principles to inform their research ...

Joint Pilot Design and Uplink Power Allocation in Multi-Cell Massive MIMO Systems [PDF]
arXiv, 2017 This paper considers pilot design to mitigate pilot contamination and provide good service for everyone in multi-cell Massive multiple input multiple output (MIMO) systems. Instead of modeling the pilot design as a combinatorial assignment problem, as in prior works, we express the pilot signals using a pilot basis and treat the associated power ...

Gender on the flightdeck: experiences of women commercial airline pilots in the UK [PDF]
, 2015 The reasons for, and the implications arising from, the underrepresentation of women on the flightdeck of commercial aircraft continues to challenge national Governments, the aviation industry, and the academic community. Although some airlines have made

Lessons from the English National Health Service new care models programme
International Journal of Integrated Care, 2019 Introduction: Between 2015 and 2018, the National Health Service (NHS) in England invested over £300m in a New Care Models (NCM) programme to develop new approaches to delivering care to whole populations.
