A Vector Network Analyzer (VNA) is used to reduce errors in equipment for Eddy Current Testing (ECT). After performing a standard 1-port calibration in the magnetic domain the measurements become practically free from drift and systematic errors and therefore easier to interpret. In addition, the li...

In this paper, statistical models are proposed to estimate trip level origin-destination (OD) matrices for public transport based on Wi-Fi data traffic. Wi-Fi monitoring equipment installed in 32 buses in Stavanger, Norway, collected Wi-Fi data during several months. The median received signal level...

To assess the implementation feasibility and provide a practical experimental validation of the filterbank multicarrier (FBMC) scheme proposed in the EMPhAtiC project, a real-time hardware demonstrator was developed using two complementary software-defined radio (SDR) design methodologies. The spect...

Aircraft equipped with satellite communication (SATCOM) systems will enable advanced Air Traffic Management (ATM) operations over datalink on a global basis. A key concept of future ATM is 4D trajectory management, which aims to ensure an optimal path and designated arrival time for the flight by in...

The requirements for data rate and capacity in wireless communication systems have increased dramatically over the last couple of decades, and it is expected that this increase will continue in the years to come. Including higher frequency bands providing additional bandwidth is a key strategy to me...

Filter bank multi-carrier (FBMC) is a candidate modulation scheme for 5G cellular mobile broadband networks. A specific domain where FBMC offers a clear advantage over other multicarrier solutions is the efficient occupancy of underutilized and fragmented spectrum. This is due to the rich spectral c...

In this paper, an experimental performance evaluation is carried out within a communication scenario that features two of the key enablers of 5G: (i) the use of post-OFDM modulations and (ii) an efficient use of the spectrum via spectrum sharing. The experimental lab set-up has been assembled so as ...

Copula models have started to be explored in wireless communications, however to date the properties they offer have not been proven or verified on real data experiments. In this paper we provide the first real evidence that the features they offer will provide beneficial modeling capabilities in wi...

We study the use of reinforcement learning to model Dynamic Spectrum Access in a realistic multi-channel environment. Three different approaches from the literature on the multi-armed bandit problem are compared on a set of realistic channel access models — two are based on stochastic models of the ...
