Abstract
The performance of cooperative spectrum sensing (CSS) with multi-slot sensing has been investigated. A number of cognitive radio (CR) enabled users sense the primary user (PU) spectrum in multiple sensing mini-slots and the decision of each slot is combined using OR rule to evaluate the local decision about PU. All the CRs send their local decisions over faded reporting channels (R-channel) to fusion centre (FC). FC takes the final decision about PU on the basis of majority logic fusion rule. The performance of spectrum sensing has been investigated in terms of detection probability and missed detection probability for different sensing parameters such as sensing threshold, number of mini-slots and sensing channel SNR (S-SNR) etc.
