Patent ID: 8254509

Claim:
A receiver which receives a reception signal subjected to orthogonal frequency division multiplexing modulation or orthogonal frequency division multiple access modulation, the receiver comprising: an array antenna having a plurality of antennas for receiving the reception signal; adaptive equalizers, each of which is provided in each of the plurality of antennas, and each of which reduces advanced waves or delayed waves having a delay time set with respect to a main wave in the reception signal; a spatial diversity combining portion which multiplies each of output signals of the adaptive equalizers by a weighting coefficient and adds the multiplied signals; a weight control portion which generates the weighting coefficient based on each of the output signals of the adaptive equalizers; and an equalizer setting unit which estimates an arrival angle for each path and a delay time for each path of the reception signal, and based on each of the estimated arrival angles and delay times of a plurality of paths, decides an interference wave for elimination to be eliminated by the adaptive equalizers among interference waves whose delay time with respect to the main wave exceeds a guard interval time, and sets in the adaptive equalizers the delay time of the interference wave for elimination with respect to the main wave.
