Adaptive antenna base station apparatus |
摘要 |
An adaptive antenna base station apparatus comprises an array antenna including N (N being a natural number) antenna elements; N reception sections for respectively performing orthogonal detection of high-frequency signals, respectively received by the antenna elements, after frequency conversion; NxM despreading sections for performing despreading operations, corresponding to delay times of M (M being a natural number) path components included in output signals of the reception sections; M correlation computing sections for performing correlations among the antenna elements for each path; a correlation combining section for combining output signals of the correlation computing sections; and a DOA estimating section for estimating a direction of arrival (DOA) by using an output of the correlation combining section. This can ensure collective estimation of DOAs of M path components, thereby reducing the amount of computation of estimating the DOAs for plural paths and the cost for the apparatus.
