MICROWAVE REPETER SYSTEM WITH SYCHRONAZING MODEM

摘要

A wireless repeater system using modem synchronization is provided to correctly acquire transmission/reception synchronization with a simple circuit by acquiring the transmission/reception synchronization of the wireless repeater system using the modem synchronization. A wireless repeater system using modem synchronization includes a wireless transmission device(20), an uplink conversion module(30), a downlink conversion module(40), and a wireless reception device(50). The wireless transmission device divides an internal reference clock period to a predetermined magnification and mixes and transmits a traffic signal with a modem signal modulated through a first modem. The uplink conversion module transmits converts a mixed signal bandwidth into a specific frequency band matched with a transmission frequency environment and transmits a converted signal through an antenna. The downlink conversion module receives a signal of the specific frequency band transmitted from the uplink conversion module through the antenna. The downlink conversion module converts and transmits the signal of the received specific frequency band into a frequency band signal matched with an internal environment. The wireless reception device divides the modem signal and the traffic signal from the signal transmitted from the downlink conversion module, and demodulates the divided modem signal through a second modem. The wireless reception device acquires the transmission/reception synchronization by adjusting a period of the internal reference clock for processing the traffic signal.
