摘要： PURPOSE: A base station synchronization apparatus in a distributed radio frequency(RF) system is provided to eliminate the need of preparing a global positioning system(GPS) receiver and a holdover stable oscillator(HOS) in all the base stations by dividing an inputted giga bit Ethernet(GE) signals and recovering an accurate synchronized signals, thereby reducing the cost in synchronizing the RF system. CONSTITUTION: A base station synchronization apparatus for synchronizing a number of base stations(312,316,318) of code division multiple access(CDMA) RF network includes a GE network for connecting the plurality of base stations(312,316,318) each other, a HSO and a GPS receiver installed in one of the base stations(312,316,318) receiving a controlled clock signal and a clock recovery part, The clock recovery part is installed in at least one of the other base stations(312,316,318) and generates a main clock signal to synchronize the at least one of the other base stations(312,316,318) by using controlled clock signal recovered from the data stream of the GE network.

摘要： There is disclosed a system and method for synchronizing a base station within a distributed radio system. A communication network is provided utilizing gigabit ethernet protocols and media. A global positioning system (GPS) is installed onboard one of a plurality of base stations. The single GPS, without the necessity for a holdover oscillator, is used to synchronize a plurality of the base stations within the network by transmitting a clock signal via the gigabit ethernet media to each base station. The gigabit Ethernet signal is tapped by a clock recovery circuit, present on each base station and the recovered signal serves as a master clock signal for the base station as well as a reference clock for the transmit and receive section.
