Abstract
Localized spectrum sensing is an alternate for database centric approaches to solve secondary use of spectrum in cognitive radios. This can be carried out by using collaborative spectrum sensing where larger amount of small devices is utilized for local spectrum sensing. This paper describes an mobile device scale implementation of multi-mode, multi-band spectrum sensor for cognitive radio. Cyclostationary feature detector algorithm is utilized to detect digital television (DVB-T/H) on UHF band and IEEE802.11a/g on 2.4/5 GHz (ISM/WLAN) bands. A miniaturized spectrum sensing device encounters physical challenges; like limited size and battery capacity, but provides opportunities to establish a dense network and fast response to dynamic chances in signal conditions.
