Summary:The present invention relates to a central control station device, a remote base station device, and a communication method for the same, which can be used for a radio over fiber (RoF) technology. Various embodiments of the present invention can provide a central control station device and a communication method, allowing an analog signal to be converted to a signal that has a carrier wave of an intermediate frequency, and the signal to be converted to a digital signal for transmission to a remote control station device. In addition, the various embodiments of the present invention can provide a remote base station device and a communication method, allowing a corresponding analog signal to be induced in a simple manner by filtering the digital signal that has the carrier wave of the intermediate frequency. 본 발명은 RoF(Radio over Fiber) 기술에 사용될 수 있는 중앙 제어국 장치, 원격 기지국 장치, 및 이들의 통신 방법에 관한 것이다. 본 발명의 다양한 실시예는, 아날로그 신호를 중간 주파수의 반송파를 가진 신호로 변환하고 이것을 디지털 신호로 변환하여 원격 제어국 장치로 전송할 수 있는 중앙 제어국 장치 및 통신 방법을 제공할 수 있다. 또한, 본 발명의 다양한 실시예는, 중간 주파수의 반송파를 가진 디지털 신호를 필터링함으로써 간이하게 대응되는 아날로그 신호를 이끌어 낼 수 있는 원격 기지국 장치 및 통신 방법을 제공할 수 있다.
