In this paper we investigate distributed spectrum sensing for cognitive radio (CR) based on multiple spectrum sensors. By using multiple spectrum sensors we explore sensing schemes based on soft information combining, hard information combining and a two-stage detection scheme that uses both soft information combining and hard information combining. The two-stage detection scheme is shown to provide improved performance compared to sensing based on either hard information combining or soft information combining alone. Computer simulation results are provided to validate the concept. |
