<p>Provided is a communication apparatus wherein the circuit scale of a communication apparatus that uses an SC-FDMA system to simultaneously receive signals from a plurality of users is reduced. Communication apparatuses (BS1, BS2), which use an SC-FDMA system to simultaneously receive signals from a plurality of users, each comprise a plurality of antennas (1a, 1b); a processing unit (6) that performs, in a frequency domain, a multi-antenna signal processing of a plurality of SC-FDMA signals received by the plurality of antennas (1a, 1b); and a user separating unit (7) that separates, based on information of user assignment in the SC-FDMA system, the signals, which have been subjected to the multi-antenna signal processing, for the respective users.</p> |
