This Letter addresses the statistical modeling of dual-polarized MIMO-LMS fading channels. In the absence of accurate experimental results, a statistical model for the characterization of MIMO-LMS channels is proposed based on consolidation of available experimental results for SISO-LMS and MIMO wireless channels as well as on their extrapolation to the(More)
The present article carries out a review of MIMObased techniques that have been recently proposed for satellite communications. Due to the plethora of MIMO interpretations in terrestrial systems and the particularities of satellite communications, this review is built on two pillars, namely fixed satellite and mobile satellite. Special attention is given to(More)
This paper presents initial results of the recently kicked-off FP7 ICT STREP project “CoRaSat” (Cognitive Radio for Satellite Communications) [1]. Focus is put on the preliminary identification of the scenarios which are suitable for the applicability of Cognitive Radio technology over Satellite Communications (SatCom). The considered(More)
Multibeam satellite networks in Ka band have been designed to accommodate the increasing traffic demands of the coming years. However, these systems are spectrum limited due to the current spectrum allocation policies. This paper investigates the potentials of applying cognitive radio techniques in satellite communications in order to increase the spectrum(More)
This paper investigates the applicability of multiple-input multiple-output (MIMO) technology to satellite communications at the Ku-band and above. After introducing the possible diversity sources to form a MIMO matrix channel in a satellite environment, particular emphasis is put on satellite diversity. Two specific different topics from the field of MIMO(More)
Aging people are in risk of social isolation due to direct or indirect effects of aging. Social isolation decreases the quality of life, health and acts against independent living, which is important for both the elderly people and society. Social networking can provide elders a sense of presence with their relatives, friends and healthcare personnel which(More)
This paper addresses scenarios of integrated satellite-terrestrial Future Internet networks based on the Information-Centric Networking (ICN) communication paradigm. Focus is given on three integration scenarios: i) Hybrid Broadcast IPTV, paving the way for SatCom integration within the Future Media Internet; ii) Smart M2M Transport, paving the way for(More)
