<p>Adaptive array processing of reception signal vector X(t) from array antennas (#1 to #4) is performed by a user signal processing part (USP). The frequency offset quantity (ΔΥ)is estimated based on an output signal y(t) from an adaptive array and a reference signal. A swap detection part (SDP) detects a swap based on the estimated frequency offset quantity (ΔΥ), error generation frequency, etc.</p> |
