Abstract
The use of “cognitive radio” (CR) technology is viewed as the key technology to fully utilize the bandwidth. In this paper, a CR-based dynamic spectrum access (DSA) device named fuzzy active period adaptor (FAPA) is proposed in a downlink transmission of IEEE 802.16h systems. FAPA decides the active period of IEEE 802.16h system to efficiently coexist with a WLAN system in unlicensed spectrum. Simulation results show that the fuzzy active period adaptation improve the overall throughput, and reduce the idle time of the spectrum.
