Method of timing and timing calibration of base station radio frequency remoter and its use

This invention relates to a method for a base station RF zoom-out timing and timing calibration and its usage, in the communication system between a wireless base station divided by the analog IF part and connected by the set wire and wireless two-way transmission measures and the front device of the far-end analog T-R processors near the T-R antenna, interface units are set between the base band digital signal process part of the base station and the antenna interface of the RF T-R processor front, the base station sends a test signal to the RF T-R processor front at the working state and receives the feedback signals to get the total time delay value on the entire T-R loop by comparing the T and R signals to be taken as the lead of timing and timing calibration between the base station and the front device of the RF T-R processor together with the front and the transformation time delay to realize total network synchronization and accurate position of UE.
