Abstract

The primary task in any cognitive radio (CR) network is to dynamically explore the spectrum and determine spectrum band that can be used without causing interference to other users. In this paper, we propose a multistage filter banks to sense the spectrum band. Compared with the conventional filter banks, our proposed method has low complexity but high detection precision. The proposed scheme has been analyzed and tested through simulations on wireless microphone detection in IEEE 802.22 WRAN.
