    • A simple cross correlation switched beam system (XSBS) for angle of arrival estimation 

      Badawy A.; Khattab T.; Trinchero D.; Elfouly T.M.; Mohamed A. ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)
      We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with ...

    • Denoising of acoustic partial discharge signals corrupted with random noise 

      Hussein, Ramy; BashirShaban, Khaled; El-Hag, Ayman H. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)
      Power transformers are one of the most important and expensive electrical equipment that require online condition monitoring. Partial discharge (PD) measurement is considered the most effective and non-destructive approach ...

    • Detecting the greedy spectrum occupancy threat in cognitive radio networks 

      Ma, Songjun; Peng, Yunfeng; Wang, Tao; Gan, Xiaoying; Yang, Feng; ... more authors ( IEEE Computer Society , 2014 , Conference Paper)
      Recently, security of cognitive radio (CR) is becoming a severe issue. There is one kind of threat, which we call greedy spectrum occupancy threat (GSOT) in this paper, has long been ignored in previous work. In GSOT, a ...
