CDMA2000 1x EV-DO空中接口演进分析

Air Interface Evolution of CDMA2000 1x EV-DO System

随着无线通信技术的不断进步,各种移动通信标准也得到了快速的发展。本文首先介绍了CDMA2000 1x EV-DO系统空中接口演进的历程,然后详细分析了AIE两个阶段相关标准的特点和关键技术,第一阶段代表标准EV-DO Rev.B和第二阶段标准UMB,并重点阐述了UMB系统物理层超帧结构。

With the improvement of wireless communication technology,the 3G mobile technology standard has gotten a rapid development. This article firstly introduces the Air Interface Evolution （AIE） course of CDMA2000 1 x EV-DO system and then analyses the characteristics and key technologies of AIE two phases standards EV-DO Rev. B and UMB,in which it expounds emphatically the physical layer superframe structure in UMB system.
