Based on both the research on the impact of CRH high-speed train on CDMA wireless communications and the experiences of planning and optimization in HU-HANG high-speed rail, a brief operation method called AHSD (Air High-Speed Direction) is summarized for CDMA network planning and optimization in high-speed rail in plain area. Well combined with theoretic and optimization practice, this method presents precise parameters for network planning and optimization so that it can be generalized conveniently.
