    摘要: Disclosed is a signal combining apparatus and a resource allocation method using the same in a cellular system using distributed antennas. The resource allocation method includes detecting a channel transmission capacity when a signal is transmitted from a single Relay Station (RS) to a Mobile Station (MS), by a Base Station (BS), detecting a channel transmission capacity when transmitting a signal produced by using signal combining by two or more RSs to the MS, by the BS, selecting a channel transmission capacity with a larger gain between the detected channel transmission capacity of the single RS and the detected channel transmission capacity of the two or more RSs, by the BS; and selecting the signal transmitted by the single RS or the signal produced by using the signal combining by the two or more RSs having the selected channel transmission capacity with the larger gain, and then transmitting the selected signal to the MS.

The remote station includes a block for dividing each of a downlink optical signal carrying service data and an optical signal carrying transmission/reception control information of the RoF wired relay system, which are input from a base station, a gain controller for separating an uplink Radio Frequency (RF) signal input from an antenna or a portion of a downlink RF signal output from a High-Power Amplifier (HPA) and for monitoring the strength of the input and output RF signals in order to control a gain of the LNA. A converter mutually converts an optical signal and an RF signal, an amplifier amplifies the converted RF signal, and an RF signal flow controller automatically controls uplink and downlink transmission paths of the amplified RF signal according to a transmission/reception status of the RoF wired relay system.
