摘要

伴隨著不斷提升的有線網路頻寬及日益增加的多媒體網路應用服務，人們與網路關係更加密切，這需求也反應到無線通訊技術上。第四代(4G; 4th Generation) 行動通訊標準將在低移動速率或靜態環境中提供高達1Gbps的傳輸速率及在高速移動環境中提供高達100Mbps的傳輸速率。4G行動通訊系統由於對頻譜使用效率、系統涵蓋率及傳輸率的高度要求，在系統設計上會與傳統行動通訊系統大不相同，當中包括大量佈設家用基地台(Femto Base Station)；利用連接寬頻有線網路來提供小範圍的無線網路傳輸服務，用以改善室內無線傳輸訊號嚴重衰減的問題。如何在現有的大基地台(Macro Base Station )的環境下佈放家用基地台以達到最高的訊號品質與系統容量，及如何在大基地台與家用基地台間、家用基地台與家用基地台間做最有效的頻譜共享、無線資源分配、干擾管理以及功率控制皆是重要的關鍵技術。
本論文在第四代行動通訊網路的環境中，提出不同的無線資源分配策略與功率控制方法以改善系統效能上，並探討使用者在不同的無線資源分配策略與功率控制下的效能，系統容量的差異程度。

With the network bandwidth and the multimedia network service continuously upgrade, people have the closer relationship with the network. The fourth-generation (4G) mobile communication system is envisioned to provide up to 1Gbps transmission rate for low-mobility and up to 100Mbps transmission rate for high-mobility. Due to the very extreme requirements on spectrum efficiency, coverage and transmission rate, the system design of the 4G system is very different from the traditional mobile communication system, including the deployment of the numerous number of Femto Base Station which uses the wired network in the backbone to provide wireless internet services in the indoor environment to lower the attenuation of wireless transmission signal in the indoor environment. The key challenges in the design of femtocell system including how to deploy femtocells in the existing mobile so that the highest signal quality and system capacity can be achieved? how to make the most effective spectrum sharing between the macrocells and the femtocells? and how to carry out the allocation of radio resources and the interference management in an effective way. In this thesis, we propose a method which improves the system efficiency, performance and system capacity by different allocation of radio resources and power-control.
