Low complexity GFDM receiver for Frequency-Selective Channels

Low complexity GFDM receiver for Frequency-Selective Channels. IEEE Communications Letter. April 2019. Wheberth Dias, Luciano Mendes, Joel Rodrigues Abstract Generalized frequency division multiplexing (GFDM) is a new waveform that can play an important role in some 5th generation (5G) mobile wireless networks scenarios, such as 5G for remote areas. It […]

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 […]
