Journal Article
Fanan, A., Riley, N., Mehdawi, M., & Alfahad, O. (2017). Performance of a TV white space database with different terrain resolutions and propagation models. Telfor Journal, 9(2), 80-85. https://doi.org/10.5937/telfor1702080f

Cognitive Radio has now become a realistic option for the solution of the spectrum scarcity problem in wireless communication. TV channels (the primary user) can be protected from secondary-user interference by accurate prediction of TV White Spaces...

Design of Cognitive Radio Database using Terrain Maps and Validated Propagation Models (2017)
Journal Article
Fanan, A. M., Riley, N., & Mehdawi, M. (2017). Design of Cognitive Radio Database using Terrain Maps and Validated Propagation Models. Advances in science, technology and engineering systems journal, 2(6), 13-19. https://doi.org/10.25046/aj020602

Cognitive Radio (CR) encompasses a number of technologies which enable adaptive self-programing of systems at different levels to provide more effective use of the increasingly congested radio spectrum. CRs have potential to use spectrum allocated to... Read More about Design of Cognitive Radio Database using Terrain Maps and Validated Propagation Models.

Spectrum occupancy survey In HULL-UK For cognitive radio applications: Measurement & analysis (2013)
Journal Article
Mehdawi, M., Riley, N., Paulson, K., Fanan, A., & Ammar, M. (2013). Spectrum occupancy survey In HULL-UK For cognitive radio applications: Measurement & analysis. International Journal of Scientific and Technology Research, 2(4), 231-236

Efficient use of the radio spectrum is a necessity for future wireless systems. Cognitive Radio (CR) systems promise large inc reases in spectral efficiency. An important design constraint for systems is understanding of the current use of frequency...

Reduced-size circularly polarised square microstrip antenna for 2.45 GHz RFID applications (2012)
Journal Article
Nguyen, D., Paulson, K., & Riley, N. (2012). Reduced-size circularly polarised square microstrip antenna for 2.45 GHz RFID applications. IET Microwaves Antennas and Propagation, 6(1), 94-99. doi:10.1049/iet-map.2011.0269

This study proposes a new design of circular polarised (CP), microstrip (patch) antenna using a set of slits and slots to effectively reduce the area of patch by 67% compared with the conventional, corner truncated, circular polarised square patch. T... Read More about Reduced-size circularly polarised square microstrip antenna for 2.45 GHz RFID applications.
