Multiple Spoofer Detection for Mobile GNSS Receivers Using Statistical Tests

open access: yesIEEE Access, 2021
We consider Global Navigation Satellite Systems (GNSS) spoofing attacks and devise a countermeasure appropriate for mobile GNSS receivers. Our approach is to design detectors that, operating after the signal acquisition, enable the victim receiver to ...

Channel Estimation in Massive MIMO Under Hardware Non-Linearities: Bayesian Methods Versus Deep Learning

open access: yesIEEE Open Journal of the Communications Society, 2020
This paper considers the joint impact of non-linear hardware impairments at the base station (BS) and user equipments (UEs) on the uplink performance of single-cell massive MIMO (multiple-input multiple-output) in practical Rician fading environments ...

Pushing the Wireless Data Rate to the Internet Speed

open access: yesIEEE Access, 2016
This paper intends to answer the question how to achieve wireless data rates that can catch up with current Internet speed, from a basic physics point of view. It is shown that the traditional electric circuit theory and design methodology that have been

Probabilistic Cooperation of a Full-Duplex Relay in Random Access Networks

open access: yesIEEE Access, 2017
In this paper, we analyze the probabilistic cooperation of a full-duplex relay in a multiuser random-access network. The relay is equipped with on/off modes for the receiver and the transmitter independently.

Improving the capacity of the ping-pong protocol

open access: yes, 2003
We present a quantum communication protocol which keeps all the properties of the ping-pong protocol [Phys. Rev. Lett. 89, 187902 (2002)] but improves the capacity doubly as the ping-pong protocol.
