摘要: 無線通訊在現今社會中已越來越重要,人們對行動通訊的依賴也比從前來的高。在無線通道中,通道的狀況對使用者具有時變性和頻率選擇性,正交分頻多工的技術因應而生,也已經被使用在一些無線通訊的規格當中,像是WiMAX 802.16e。而在頻寬及時間都是有限的情況下,如何將這些有限的資源做最佳的分配成為今日重要的課題。在本篇論文裡,我們提供了一個在802.16e規格下設計的演算法,其最終目的是希望在盡量滿足所有使用者的服務品質需求的情況下,提高整個頻寬和時間的使用效率, 達到資源的最佳利用。
Wireless communication has become increasingly important in the nowadays society, and people have more dependence on mobile communication than before. In wireless channels, the channel state changes over time and frequency for users so that the orthogonal frequency division multiple access (OFDMA) technology is coming up and being used in current wireless broadband access standards, for example, 802.16e WiMAX. In the case of time and bandwidth are limited, how to allocate the limited resource in the best way has become an important issue. In this thesis, we provide an algorithm designed under the 802.16e standard, the ultimate goal is to try to satisfy all users’ Quality of Service (QoS) requirements, raising the efficiency of using time and bandwidth to achieve optimal utilization of resources.
