The change of surrounding environments affects communication quality largely in wireless communications. The conventional communication fixing a communication mode cannot follow the change of environments and deteriorates communication performance. Cognitive radio can adapt to the change of environments and attracts attention. This paper discusses the realization and the evaluation of cognitive radio in OFDM communication. As a technique for cognitive radio in this research, we propose an environmental-adaptive agent system, which records the results of communication experiments as a database beforehand and decides the best communicate mode from the database. The effectiveness of the proposal method has been demonstrated by the simulation assuming variable wireless environments. The throughput performance has been evaluated by comparing fixed radio, link adaptation, and the proposed method. |
