Wide-band Transmission System and Signal Transmission Method In the System

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). 본 발명은 송신단에서 대역통과 필터링하고 광전송 용량을 넘지 않도록 데이터 정렬 처리하고 나서 신호를 광 전송함으로써, 시스템의 시간 지연을 줄이도록 한 광대역 전송시스템 및 신호 전송 방법에 관한 것이다. 본 발명의 광대역 전송시스템은, 광대역 전송시스템에 있어서, 입력되는 아날로그신호를 디지털신호로 변환한 후에 상기 변환된 디지털데이터를 대역통과 필터링하고 광 전송용량에 맞게 정렬하여 전송하는 송신수단과; 상기 송신수단으로부터 수신되는 디지털데이터를 보간 처리한 다음에 대역통과 필터링하고 나서 아날로그데이터로 변환하는 수신수단을 포함하여 구성된다.
