BROADBAND TRANSFER SYSTEM AND SIGNAL TRANSMITTING METHOD

摘要

PURPOSE: A broadband transfer system and a signal transmitting method are provided to facilitate cell planning by positioning a remote unit at a farther distance and make a smooth handoff with respect to an adjacent base station and a repeater. CONSTITUTION: An analog/digital converter(21) converts an analog signal received from a base station into a digital signal. A digital signal processor(22A) performs a bandpass filtering on the digital signal, aligns it according to optical transmission capacity, and transmits it to an optic transmitter(23). The optical transmitter(23) optically transmits the received signal to a remote unit(30a). An optic receiver(24) photoelectric-converts the signal received from the remote unit(30A). A digital signal processor(25A) interpolates it and then bandpass-filters it. Thereafter, a digital/analog converter(26) converts it into an analog signal and transmits it to the base station. An optic receiver(31) photoelectric-converts the signal received from a doner unit(20A). A digital signal processor(32A) interpolates it and bandpass-filters it. A digital/analog converter(33) converts it into an analog signal and radiates toward a terminal through an antenna. An analog/digital converter(34) converts the analog signal received from the terminal into a digital signal. An optic transmitter(36) bandpass-filters the digital signal, aligns it according to optical transmission capacity, and then transmits it to an optic transmitter(36). Then, the optic transmitter(36) transmits it to the doner unit(20A).
