  • Cooperative prediction for cognitive radio networks 
    Barnes, Simon Daniel; Maharaj, Bodhaswar Tikanath Jugpershad; Alfa, Attahiru Sule (Springer, 2016-08)
    Combining spectrum sensing (SS) and primary user (PU) traffic forecasting provides a cognitive radio network with a platform from which informed and proactive operational decisions can be made. The success of these ...
  • Prediction based channel allocation performance for cognitive radio 
    Barnes, Simon Daniel; Maharaj, Bodhaswar Tikanath Jugpershad (Elsevier, 2014-04)
    The interdependency, in a cognitive radio (CR) network, of spectrum sensing, occupancy modelling, channel switching and secondary user (SU) performance, is investigated. Achievable SU data throughput and primary user (PU) ...
  • Spectral occupation of TV broadcast bands : measurement and analysis 
    Barnes, Simon Daniel; Botha, P.R. (Philippus Rudolph); Maharaj, Bodhaswar Tikanath Jugpershad (Elsevier, 2016-11)
    The findings of a TV broadcast spectrum measurement campaign, performed at six different locations on the Hatfield campus of the University of Pretoria, are presented. Since the use of television white spaces (TVWS) could ...
  • Spectrum occupancy investigation : measurements in South Africa 
    Barnes, Simon Daniel; Jansen van Vuuren, P.A.; Maharaj, Bodhaswar Tikanath Jugpershad (Elsevier, 2013)
    Regulatory bodies have predicted an impending shortage in commercial radio frequency spectrum in the near future. However, due to outdated regulatory practices, many of these bands are in fact inefficiently underutilised. ...
