Abstract  Abstract

Interference of multiplexed signals is reduced in an MC-CDMA communication system. A wireless communication apparatus performing a wireless communication by combining a multicarrier transmission system with a spread spectrum includes: a rearrangement control part that ranks each subcarrier in accordance with a magnitude of received power based on received power information indicating received power of each subcarrier received from a communicating apparatus and groups subcarriers in descending or ascending order of the rank in accordance with a spreading factor; and a rearrangement part that distributes a spread code to each of the groups.
