碩士 === 國立東華大學 === 電機工程學系 === 104 === Due to the rapid growth of wireless networks and the requirement on the quality of service (QoS), the improvement of the spectrum utilization efficiency under busy and congested urban environment has become an important issue. Cognitive radio (CR) is the best technique to fulfill this task. Without affecting the transmission of the primary users (PUs), the secondary users (SUs) can detect the idle channels and send their information via these channels. The theories of economics were used in some previous research to improve the spectrum utilization efficiency. In this thesis, the auction theory is incorporated into CR for the allocation of channels so that the number of users can be increased and the efficiency can be enhanced. The results are further compared with those from the general allocation of channels in CR. Keywords : Cognitive radio ; Auction theory
