A Fast Method for Downlink Cell Search in TD-SCDMA
TD-SCDMA cell search is performed in three scenarios: downlink guide slot (DwPTs) position search, downlink synchronization code (SYNC_DL) position search and frame synchronization control. A fast method for every scenarios of downlink cell search in TD-SCDMA is proposed. Based on characteristics of frame and slot structure in TD-SCDMA, power-matching stencil method is used to find the position of downlink guide slot (DwPTs) and definition stencil method is proposed to decide the position of downlink synchronization code (SYNC_DL). Moreover, the problem of channel estimation for TD-SCDMA mobile communication system is investigated and a new fast method for detecting downlink guide channel is derived to control frame synchronization. This new method simplifies calculation complexity, realizes fast and high efficiency network test system and can be applied to TD-SCDMA network planning and optimization. The conclusion can be proved by simulations and field testing which are mentioned.
