Abstract
A radio communication device performing radio communication using OFDMA system includes: a SMI weight deriving unit (14) calculating a correlation matrix and a correlation vector using a plurality of received signal vectors as sample values, and deriving a SMI weight based on the calculated correlation matrix and correlation vector; and a weight multiplying unit (15) for multiplying the received signal vector by the SMI weight derived by the SMI weight deriving unit (14). The SMI weight deriving unit (14) uses a received signal vector of each of a plurality of subcarriers included in a user allocated region in the OFDMA system as a sample value, and thereby derives the SMI weight for the user allocated region.
