碩士 === 國立臺北科技大學 === 電機工程系研究所 === 101 === This thesis mainly researches into the performance improvement of adaptive resource allocation algorithms in OFDMA systems with inter-cell interference. The traditional resource allocation algorithm uses the given user’s channel responses to do resource allocation and it doesn’t consider the inter-cell interference caused by the neighbor base stations. But the inter-cell interference does affect the optimal resource allocation of systems especially for large interference. The quantity of inter-cell interference is usually computed by transmission powers of neighbor base stations and path losses due to distances between the user and neighbor base stations. In this thesis, we first build the relation between the user’s channel response and the distance between the user to the base station. And then we propose a proportional rate constraint adaptive resource allocation algorithm which considers the factor of inter-cell interference. From computer simulation, it shows that our method is better than all other algorithms for both Shannon capacity and adaptive modulation.
