<p>PURPOSE: A receiving device in a FDD(Frequency Division Duplex) system is provided to select FA in a receiving device, thereby reducing a digital IF transmission amount. CONSTITUTION: A remote RF(Radio Frequency) unit(250) senses a frequency allocation output from a neighboring base station. A remote RF unit selects lowest power FA(Foreign Agent) among the sensed FA. The remote RF unit multiples a receiving signal and a monitor signal. Based on the selected FA, there receiving signal and a monitor signal are processed. The remote RF unit transmits the selected FA and multiplexed signal to a baseband unit(270). Based on FA, a processing unit(210) processes a signal of a transmission device.</p> |
