Abstract
A reception device includes two antennas--that are in an inverse correlation, a switching unitwhich switches the signal that is to be processed among signals received by the two antennas--, and an adaptive equalizerwhich uses equalization coefficients to perform equalizing processing on the signal considered by the switching unitto be the signal to be processed, and an equalization coefficient altering unitwhich alters the equalization coefficients used by the adaptive equalizersynchronously with the timing of switching performed by the switching unit. In the reception device can reduce the required time for reconvergence of equalization coefficients stemming from reception system switching in selection diversity using an inverse correlation antenna.
