摘要： An apparatus and method for processing signals in a distributed antenna system. The method includes receiving, by a Base Station (BS), Channel State Information (CSI) from Mobile Stations (MSs) located within a coverage area of the BS or a coverage of Relay Stations (RSs) connected to the BS; multiplying signals for transmission to the MSs by beamforming vectors by using the CSI; and transmitting the multiplied signals to the MSs.

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.
