1、3G移動(dòng)通信技術(shù)研究與應(yīng)用移動(dòng)通信技術(shù)研究與應(yīng)用摘要：摘要：第三代移動(dòng)通信系統(tǒng)已在我國(guó)商業(yè)化運(yùn)營(yíng)，3G網(wǎng)絡(luò)為各種業(yè)務(wù)提供了更多的資源，3G時(shí)代的移動(dòng)業(yè)務(wù)不僅對(duì)網(wǎng)絡(luò)，同時(shí)也對(duì)終端提出了更高的要求，3G終端必須具備更快更強(qiáng)的通信和處理能力，同時(shí)還要更加人性化，更具擴(kuò)展性。本文首先簡(jiǎn)要的介紹了有關(guān)3G方面的技術(shù)術(shù)語(yǔ)、3G的發(fā)展歷程、現(xiàn)狀，以及相關(guān)的產(chǎn)業(yè)鏈等。接著詳細(xì)介紹了3G中的三大主流標(biāo)準(zhǔn)（CDMA2000、WCDMA、TD_SCDMA），

2、以及主要特點(diǎn)，主要優(yōu)點(diǎn)等，并且相互比較了它們之間的優(yōu)點(diǎn)以及不足。同時(shí)又完整的介紹了TDSCDMAWCDMACDMA2000三種不同的3G移動(dòng)通信國(guó)際主流標(biāo)準(zhǔn)，對(duì)這三種技術(shù)的特點(diǎn)作了分析和比較，論述了適合國(guó)情的自主產(chǎn)權(quán)的TDSCDMA系統(tǒng)特點(diǎn)最后介紹了3G移動(dòng)通信的發(fā)展趨勢(shì)及面臨的挑戰(zhàn)。關(guān)鍵詞：關(guān)鍵詞：WCDMA；CDMA2000；TDSCDMA；比較分析；Thesearchuseofthe3Gmobilecommunicationtec
