摘要
CDMA2000发展到1xEV-DO和1xEV-DV,对于数据帧的无误码接收和有效的差错重传控制有着越来越高的要求。1xEV-DO通过空中接口协议为无线网络的分组传输提供了可靠而有效的差错重传控制系统。EV-DO主要在物理层、应用层和MAC层中采用的差错控制技术不仅提供了良好的差错重传控制机制,同时提高了无线链路的数据吞吐量,更加符合EV-DO高速分组数据传输的要求。
From CDMA2000 to 1x EV-DO and 1x EV-DV, the requirement for errorless receiving of data frames and effective error repeated transmission control is becoming urgent. 1xEV-DO provides credibility and effective error repeated transmission control system for packet transmission in wireless network via air interface protocol. EV-DO adopts error repeated transmission control technology in physical layer, application layer and MAC layer, which not only provides favorable error repeated transmission control system but also improves data throughput of wireless link. It is more suitable for the EV-DO high speed data padket transmission.
