第三代寬頻CDMA系統3GPP上鏈基頻接收機設計與模擬

Abstract

第三代行動通訊系統可提供多樣化且高品質的語音與數據服務，因此第三代行動通訊系統的標準制訂與研究，已經成為目前通訊技術領域最重要的課題。3GPP是由數國電信標準制訂組織所組成之團體，以歐洲ETSI的UTRA方案為基礎，提出一個使用寬頻CDMA技術的第三代通訊系統標準提案。本論文首先介紹第三代行動通訊系統的特色與3GPP系統上鏈頻道的規格。我們針對上鏈頻道的架構，設計並模擬上鏈共用頻道與專用頻道之基頻接收機。利用犁耙式接收機接收資料，以對抗多重路徑的干擾。另外，我們討論脈波整形濾波器的使用，以及接收機的取樣方式對接收效能之影響。

Third-generation mobile communication system can offer a variety of high quality voice and data service. Hence the standardization and study of third-generation mobile communication system has been the most important issue in telecommunication technologies. 3GPP is an organization composed of several regional standards bodies. This thesis first introduces the features of third-generation mobile communication system and the 3GPP uplink radio access specification. Based on the uplink channel architecture, we design and simulate the uplink receivers for the uplink common and control channels. We use a RAKE receiver to combat the effects of multipath fading. We also discuss the usage of pulse shaping filters and the effects of different sampling ways on receiver performance.
