PROBLEM TO BE SOLVED: To appropriately suppress an interference wave in a multipath environment.SOLUTION: A multipath interference equalization filter selects, as a reference signal, one of a plurality of reception signals received by a plurality of antennas. A tap coefficient is calculated to minimize the power of a subtraction signal indicative of a subtraction result obtained by subtracting a signal output from each FIR filter unit, having an input of the selected reference signal from another reception signal, the multipath interference equalization filter sets the tap coefficient of a tap to zero which calculation is made after giving a delay time equal to a delay time given to the other reception signal. |
