METHOD FOR EFFECTIVELY COMBINING REPEATER WITH WIRELESS COMMON CHANNEL TRANSMITTERS TO IMPROVE ERROR CAUSED BY REPEATER IN MEASURING LOCATION OF MOBILE TERMINAL IN AFLT METHOD USING PILOT CHANNEL OF CDMA MOBILE BASE STATION

摘要

PURPOSE: A method for effectively combining a repeater with WCCTs(Wireless Common Channel Transmitters) is provided to improve an error caused by a repeater in measuring the location of a mobile terminal in an AFLT(Advanced Forward Link Trilateration) method using a pilot channel of a CDMA mobile base station. CONSTITUTION: A terminal signal, received through a service antenna, is passed through a duplexer(4021) and combined with the terminal signals received through a plurality of other service antennas at a signal combiner(4011). The combined signal is transferred to a BTS after being filtered through a repeater filter block(4001). Downlink signals, inputted to the repeater filter block(4001), are outputted to the signal combiners(4051-405n) respectively connected to the service antennas. The signal combiners(4051-405n) respectively combine the downlink output signals of the repeater filter block(4001) with the unique identity signals of WCCT modules(4041-404n) and output the combined signals to power amplifiers(4031-403n). Each power amplifier(403n) amplifies the inputted signal and outputs it to each duplexer(402n). The downlink signals, passed through the duplexers(4021-402n), are transferred to terminals through the service antennas respectively.
