摘要

An OFDM radio reception device (100) having a plurality of antennas (110-1 to 110-K) removes a guard interval CP from a reception signal and performs S/P conversion, FFT, and channel estimation of the reception signal. The OFDM radio reception device (100) performs channel equalization by multiplying the signal after the FFT by a channel response value obtained by the channel estimation. Moreover, the OFDM radio reception device (100) acquires a covariance matrix of each burst and calculates a reception weighting coefficient according to the covariance matrix. Furthermore, the OFDM radio reception device (100) accumulates the reception weighting coefficient on the signal mapped on each burst and connects the reception signals. ® KIPO & WIPO 2009
