摘要(中) 無線通訊技術在近幾年間的發展非常快速,功能強大的智慧型手機也越來越普及,各式各樣的智慧型手機應用軟體如雨後春筍般誕生,讓人們可以隨時隨地享受著其所帶來的方便和樂趣。然而,相對的也導致了無線資源短缺的艱鉅問題,為求服務更多用戶、提供更佳的服務品質以及更有效的利用資源,嚴謹的無線資源管理便是非常重要的課題。
因此本篇研究在長期演進技術(LTE)上行鏈路的單載波分頻多工(SC-FDMA)系統的架構下,提出一套新的資源分配演算法,與以往兩種常見的RME、MEG 演算法相比較,可使得具有不同傳輸速率、占用不同頻寬的各類使用者需求,都能達到更穩定、更好的服務品質。
摘要(英) Wireless communication technology has been in progress rapidly in recent years,and powerful smartphones become more and more popular.Today with so many applications for smartphone,people can enjoy the pleasure every time and every where.But it will also bring a big problem - The shortage of radio resources.To serve more users,to supply better Quality of Service , and to utilize radio resources more efficiently , it is very important to manage radio resource.
This thesis is discussed under the architecture of SC-FDMA in LTE uplink , and we propose a new resource allocation algorithm . Compared to two well-known algorithms - RME and MEG , the simulation results show that our proposed algorithm can provide much more steady and better Quality of Service to users with different requirements.
