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。
The development of CDMA2000 to 1xEV-DO and 1xEV-DV has higher and higher requirements for error-free data frame reception and effective error retransmission control. 1xEV-DO over the air interface protocol for wireless network packet transmission provides a reliable and effective error retransmission control system. The EV-DO error control technology mainly used in the physical layer, the application layer and the MAC layer not only provides a good error retransmission control mechanism but also improves the data throughput of the wireless link and is more in line with the EV-DO high-speed packet data transmission Request.
