RADIO APPARATUS AND ADAPTIVE ARRAY PROCESSING METHOD

摘要

A correlator (1030) detects arriving timings of a desired wave and an interfering wave from a signal transmitted by the OFDM scheme. A reception response vector estimator (1050) estimates a first response vector for a signal arriving within a guard interval section from the head arriving wave and a second response vector for a signal arriving after the guard interval section from the head arriving wave out of the desired wave, and also a third response vector for a signal arriving within the guard interval section from the head arriving wave and a fourth response vector for a signal arriving after the guard interval section from the head arriving wave out of the interfering wave. An adaptive array block (1070.k) provides a weight vector based on a result of Fourier transform on the first to fourth response vectors.
