Abstract(in English) Cognitive radio can recognize communication environments around radio stations and improve frequency utilization in frequency, space, time domains and communication performance by changing radio frequency and communication system dynamically. In cognitive radio, a cognitive radio engine determines a communication function by using knowledge database. In the implementation of an OFDM based cognitive radio engine, we propose a new communication system search algorithm which can keep good communication performance even for low quantity of learning. We evaluate throughput performance in the proposed algorithm by baseband simulation at working the cognitive radio engine.
