摘要:
An adaptive antenna radio communication device comprises a divided band direction estimating unit for estimating the direction by calculating the cross correlations between a pilot signal and sub-carrier signals of the respective divided bands received by an array antenna and calculating a spatial profile from correlation matrices determined by combining the correlation values between antenna elements of the different sub-carriers according to the output of the cross correlation calculation; a divided band array weight creating unit for creating a weight of a receive array having a directional beam in the direction of estimation for each divided band; and a sub-carrier directivity creating unit for creating a directivity by multiplication-combining the created receive array weight with the corresponding sub-carrier signal.
