abstract
Spectrum sensing is an essential task for cognitive radios (CRs) and next generation wireless networks (NGWNs). In this study, an experimental setup which can emulate a spectrum sensing scheme through the use of energy detector is proposed. Both line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios are considered. NLOS scenarios take into account the light and heavy shadowing cases as well. The impact of having perfect spectral knowledge on the performance of spectrum sensing is also studied. Results and relevant discussions are given. Conclusions and future directions are outlined. 2011 ACM.
