Abstract
Reliable spectrum sensing is one of the key technologies for enabling
cognitive communications. In this paper, spectrum sensing based on Welch
periodogram is applied to a femtocell scenario where cognitive femto base
station (FBS) is located in the same frequency band as the surrounding
macrocell and neighboring femtocells. Parameters for the femtocell simulations
are selected based on 3G Partnership Project (3GPP) contributions to tie this
work to on-going femtocell standardization work. Different interference
scenarios are also discussed. Spectrum sensing based on Welch periodogram is
presented, and two scenarios including a user equipment (UE) located indoor
and outdoor are selected for further study. The results, given as receiver
operation characteristic (ROC) curves, clarify the practical regions inside of
which spectrum sensing is capable of providing reliable results for sensing
the presence of the MUE.
