dc.description.abstract | 隨著無線網路傳輸需求量日益增加,異質網路是目前在個人通訊系統當中被廣泛討論的技術之一,其利用縮小細胞之大小以發揮空間重用的特性進而增加系統中在頻譜使用上的效率。然而這種優勢會因為基地台之間在距離與傳輸功率上的差異所額外產生的干擾而受到限制,這使得在此種技術被廣泛運用之前,必須針對頻譜使用效率和接收訊號品質之間去做到比較好的權衡。針對這個問題,近年來的相關研究中,主要是分別透過頻率分配和傳輸功率控制來提供解決辦法,而大多數的研究都把重點放在避免干擾本身的產生,並未考慮干擾在使用者之間因為使用網路內容之差異性所造成的影響程度亦不相同。而本篇提出了一種以使用者為導向的機制,在不對其他使用者感受到的服務品質造成太嚴重的影響之下,盡可能的對功率及頻寬資源去做重複利用,以達到系統最大之使用效率。而在網路模擬中的結果也顯示出我們提出的方法能比其他採用比較保守之方式去分配資源的方法更能有效地運用系統資源而使異質網路本身所帶來的優勢更能有發揮的空間。 | zh_TW |
dc.description.abstract | As the demand of wireless communication increases, heterogeneous network is one of the techniques which are widely discussed. Through microizing the cell size, the radio spectrum can be further reused and thus improve the spectral efficiency. However, new types of inter-cell interference that associated with the positions and the transmission power difference of base stations would degrade the advantages brought from heterogeneous network. As a result, more concern with the tradeoff between spectral efficiency and the signal quality is required. For this problem, most works used power control or spectrum allocation to focus on the avoidance of interference but the actual effects of interference on users are not considered, which has much to do with users’ network content. In this paper, we proposed a victim-based method, which reuses resources as many as possible while minimizing the impact on users’ perceived service quality. The simulation results also showed the proposed method can utilize resources more efficiently than other conservative schemes and thus improve the system performance. | en |
