Abstract

Cognitive radio systems provide dynamic spectrum access, which is expected to improve frequency use efficiency. These systems need a sensing function to avoid interference from other radio stations. However, it is impossible to completely avoid interference because no perfect sensing function has been developed. To solve this problem, we propose using a new cognitive radio system with three main functions: cooperative sensing, interference alerting, and frequency management. We developed and evaluated a prototype of the system and found that the system is effective.
