A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications (2013)
Conference Proceeding
Zolfaghari, M., Riley, N. G., Mahdawi, M., & Shen, J. (2013). A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications. doi:10.1109/lapc.2013.6711973

The paper presents a co-planar wave guide (CPW)-fed slot loaded low return loss planar printed antenna with a small size designed for wireless communication and UWB applications. First, a conventional UWB antenna is modeled to provide a reference poi... Read More about A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications.

Cooperative wideband spectrum sensing with multi-bit hard decision in cognitive radio (2013)
Conference Proceeding
Mehdawi, M. A., Riley, N. G., Ammar, M., Fanan, A., & Zolfaghari, M. (2013). Cooperative wideband spectrum sensing with multi-bit hard decision in cognitive radio. https://doi.org/10.1109/TELFOR.2013.6716212

Cognitive radio offers an increasingly attractive solution to overcome the underutilization problem. A sensor network based cooperative wideband spectrum sensing is proposed in this paper. The purpose of the sensor network is to determine the frequen... Read More about Cooperative wideband spectrum sensing with multi-bit hard decision in cognitive radio.

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...
