摘要

A pilot diversity scheme that improves the functionality of a CDMA system by combining pilot channels and pilot symbols in the forward direction of a DS / CDMA system that can meet the demand for forward capacity maximization of a DS / CDMA system and maximizes the capacity of a subscriber System is disclosed. By using both the pilot channel and the pilot symbol in the forward direction, the advantages of the inter-base station synchronization system using the pilot channel are utilized for the handoff and the initial synchronization, and the periodic phase prediction is performed using the pilot symbol for the detection of the traffic channel. Therefore, since the pilot channel is used only for the initial synchronization and the like, the power of the pilot channel is lowered after initial synchronization using the pilot channel, so that the interference of the pilot channel on the traffic channels in the forward direction by a small amount of power Can be minimized.
