【摘要】 作为第三代移动通信系统主流方案之一的edma2000 1x EV-DO系统,为用户提供了高速率分组数据业务服务。1x EV-DO Realese A标准是CDMA空口协议IS-856的演进版本,其目的旨在进一步提高分组数据通信,通过利用最先进的编码技术和一些关键技术,如:前向调度算法,反向速率控制算法,反向功率控制算法, 使得1x EV-DO Realese A前向链路支持的峰值速率达到3.1 Mbps,反向链路支持的峰值速率达到1．8Mbps。与 cdma2000 1x EV-DO Rel 0支持的前、反向峰值速率分别为2．4Mbps和153．6kbps相比,更好的满足了高速数据业务的需求。本文重点讨论的是cdma2000 1x EV-DO Realese A系统仿真模型的设计,通过仿真证明模型设计的正确性和通用性,与3GPP2测试标准给出的仿真数据相比,在相同的PER条件下,本文的仿真模型可以获得较优的Eh／Nt(dB)。更多还原

【Abstract】 CDMA2000 lx EV-DO is one of the major schemes of 3G communication systems. It can support high rate packet data services to uesrs. The lx EV-DO Realese A standards is an evolution of the IS-856 of CDMA air interface standards developed specifically for packet data communications, and ulilizes the most advanced coding techniques and some key techniques such as forward link scheduler, reverse link rate control arithematic, reverse link power control arithematic and high level coding technique in order to provide up to 3.1 Mbps peak data rate on the forward link and 1.8 Mbps peak data rate on the reverse link. Compared to the 2.4 Mbps peak data rate on the forward link and 153.6kbps peak data rate on the reverse link of cdma2000 lx EV-DO Rel O system, it can be much better to satisfy the high rate packet data service. This paper details in simulation model design of the cdma2000 1x EV-DO Realese A System. The simulation results shows that the simulation model is basically correct and universal, the results of Eb/ Nt(dB) are a little better than the test criterion given by 3GPP2 in the same PER.更多还原
