Pilot- and CP-Aided Channel Estimation in MIMO Non-Orthogonal Multi-Carriers
Abstract. Motivated by 5G application requirements that challenge the use of orthogonal frequency division multiplexing (OFDM), non-orthogonal multi-carriers are being investigated. Unlike OFDM that takes advantage of orthogonal pilot observation, in non-orthogonal waveforms, pilots are contaminated by interference from multiple dimensions, i.e., inter-subsymbol-, inter-carrier-, and inter-antenna-interference, when multiple-input-multiple-output (MIMO) is also part of the transmission. Employing […]

NFV orchestration on intermittently available SUAV platforms: challenges and hurdles
Abstract. In this paper, we analyze the main challenges and issues related with the orchestration of Virtualized Network Functions (VNFs) on Small Unmanned Aerial Vehicles (SUAVs). Our analysis considers a reference scenario where a number of SUAVs are deployed over a delimited geographic area and provide a mobile cloud environment that supports the deployment of functionalities using Network Functions Virtualization (NFV) […]

Instantaneous Spectral Analysis
Instantaneous Spectral Analysis. Journal of Communication and Information systems. January 2019. Jerrold Prothero, KM Zahidul Islam, Henry Rodrigues, Luciano Mendes, Jon Barrueco, Jon Montalban Abstract The standard Fourier Transform (FT) can be seen as a change of basis in which a “time domain” amplitude sequence is re-expressed as a sum of sinusoids with constant coefficients […]

Experience: Implications of Roaming in Europe
Experience: Implications of Roaming in Europe Abstract: “Roam like Home” is the initiative of the European Commission (EC) to end the levy of extra charges when roaming within the European region. As a result, people are able to use data services more freely across Europe. However, the implications roaming solutions have on performance have not been […]

Enabling Multi-Mission Interoperable UAS Using Data-Centric Communications
Abstract. We claim the strong potential of data-centric communications in Unmanned Aircraft Systems (UAS), as a suitable paradigm to enhance collaborative operations via efficient information sharing, as well as to build systems supporting flexible mission objectives. In particular, this paper analyzes the primary contributions to data dissemination in UAS that […]

Sparse Code Multiple Access applied in the Generalized Frequency Division Multiplexing
Abstract. The main objective of this paper is to show the performance of the non-orthogonal multiple access scheme named sparse code multiple access (SCMA) when it is applied in a non-orthogonal physical layer transmission technique, more specifically, in the generalized frequency division multiplexing (GFDM). The performance analysis is made in terms of the […]
