cdma移動通信系統(tǒng)切換技術(shù)的研究

1、CDMACDMA移動通信系統(tǒng)切換技術(shù)的研究移動通信系統(tǒng)切換技術(shù)的研究摘要：摘要：本文章對CDMA技術(shù)的發(fā)展歷史做了詳細(xì)的論述和介紹，后分別對TDSCDMA和CDMA2000的應(yīng)用進(jìn)行簡單的介紹。本文將對CDMA技術(shù)的基本原理以及CDMA系統(tǒng)中的切換種類以及各種切換方式產(chǎn)生的情況以及各種切換方式的比較分別作為重要的論述內(nèi)容。CDMA技術(shù)中將對軟切換技術(shù)的切換條件、過程、參數(shù)等作為重點(diǎn)研究，探討不同切換參數(shù)對通話效果和網(wǎng)絡(luò)的影響，并結(jié)合CD
