<p><P>PROBLEM TO BE SOLVED: To reduce the amount of interface signals between a baseband unit and a remote radio unit while restraining a signal quality from deteriorating and restraining a scale of signal processing particularly in the remote radio unit form increasing in an OFDM radio. <P>SOLUTION: A signal frequency of an interface signal between a baseband unit and a remote radio unit is decreased by downsampling, and the distortion of the signal caused by downsampling is compensated for each subcarrier before Inverse FFT processing during transmission, and after FFT processing during reception. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
