畢業(yè)設計（論文）-3g移動通信技術研究與應用

1、3G移動通信技術研究與應用移動通信技術研究與應用摘要：摘要：第三代移動通信系統(tǒng)已在我國商業(yè)化運營，3G網絡為各種業(yè)務提供了更多的資源，3G時代的移動業(yè)務不僅對網絡，同時也對終端提出了更高的要求，3G終端必須具備更快更強的通信和處理能力，同時還要更加人性化，更具擴展性。本文首先簡要的介紹了有關3G方面的技術術語、3G的發(fā)展歷程、現(xiàn)狀，以及相關的產業(yè)鏈等。接著詳細介紹了3G中的三大主流標準（CDMA2000、WCDMA、TD_SCDMA），

2、以及主要特點，主要優(yōu)點等，并且相互比較了它們之間的優(yōu)點以及不足。同時又完整的介紹了TDSCDMAWCDMACDMA2000三種不同的3G移動通信國際主流標準，對這三種技術的特點作了分析和比較，論述了適合國情的自主產權的TDSCDMA系統(tǒng)特點最后介紹了3G移動通信的發(fā)展趨勢及面臨的挑戰(zhàn)。關鍵詞：關鍵詞：WCDMA；CDMA2000；TDSCDMA；比較分析；Thesearchuseofthe3Gmobilecommunicationtec
