  • Лапо ( Lapo ), Петр ( Piotr ) (Современная библиотека, 2016)
    В настоящее время популярным подходом в определении приоритетов развития публичной библиотеки в среде мегаполиса является рассмотрение ее в качестве так называемого «третьего места». В статье анализируется, насколько ...
  • Liu, Huidong; Chen, Jin; Ding, Guoru; Tsiftsis, Theodoros A.; Rowell, Corbett (2016)
    In this paper, a cooperative cognitive radio network (CRN) with energy harvesting capabilities of its secondary users is considered. Specifically, cooperative spectrum sensing and multi-antenna beamforming are employed ...
  • Bagheri, Alireza; Sofotasios, Paschalis C.; Tsiftsis, Theodoros A.; Ho-Van, Khuong; Loupis, Michael I.; Freear, Steven; Valkama, Mikko (2016)
    Energy detection has been for long constituting the most popular sensing method in RADAR and cognitive radio systems. The present paper investigates the sensing behaviour of an energy detector over Hoyt fading channels, ...
  • Tsinos, Christos G.; Foukalas, Fotis; Tsiftsis, Theodoros A. (2016)
    In this paper a novel Carrier Aggregation (CA) scheme is proposed for downlink MIMO LTE-A Systems. The proposed approach achieves increased transmission rates by establishing the communication links via both licensed ...
  • Miridakis, Nikolaos I.; Tsiftsis, Theodoros A.; Alexandropoulos, George C.; Debbah, M´erouane (2016)
    A dual-hop cognitive (secondary) relaying system incorporating collaborative spectrum sensing to opportunistically switch between data transmission and energy harvesting is introduced. The secondary relays, first scan ...
