  • Assylbekov, Zhenisbek; Washington, Jonathan; Tyers, Francis; Nurkas, Assulan; Sundetova, Aida; Karibayeva, Aidana; Abduali, Balzhan; Amirova, Dina (DOI: 10.13140/RG.2.2.12467.43045, 2016-04)
    This paper presents the results of developing a morphological disambiguation tool for Kazakh. Starting with a previously developed rule-based approach, we tried to cope with the complex morphology of Kazakh by breaking ...
  • 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 ...
  • Valagiannopoulos, Constantinos A.; Simovski, C. R.; Tretyakov, Sergei A. (2016-09)
    The speed with which electromagnetic energy can be wirelessly transferred from a source to the user is a crucial parameter for performance of a large number of electronic and photonic devices. In this presentation we ...
  • 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, ...
  • 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 ...
  • Assylbekov, Zhenisbek; Myrzakhmetov, Bagdat; Makazhanov, Aibek (The 4-th International Conference on Computer Processing of Turkic Languages “TurkLang 2016”, 2016)
    Sentence alignment is the final step in building parallel corpora, which arguably has the greatest impact on the quality of a resulting corpus and the accuracy of machine translation systems that use it for training. ...
  • Qi, Nan; Xiao, Ming; Tsiftsis, Theodoros A.; Cao, Phuong L.; Skoglund, Mikael; Li, Lixin (2016)
    In this paper, the energy efficiency (EE) of a cooperative diversity system with maximum diversity network coding (MDNC) is studied. In the considered system, channel state information (CSI) is only available at the ...
  • 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)
    We present a multi-user multiple-input multipleoutput (MIMO) cognitive radio system consisting of a secondary receiver that deploys spatial multiplexing to decode signals from multiple secondary transmitters, under the ...
