Patent ID: 8335273

Claim:
A control apparatus for an equalizer that equalizes a reception signal by controlling a weighting-adding on a received sequence based on a correlation between a signal sent from a first wireless base station and an interference signal from a second wireless base station to the signal, the control apparatus comprising: a estimator that determines a first channel estimation value regarding the first wireless base station based on a first signal from the first wireless base station, determines a second channel estimation value regarding the first wireless base station based on a second signal received in the same timing as the first signal from the first wireless base station, determines a third channel estimation value regarding the second wireless base station based on a third signal from the second wireless base station, and determines a fourth channel estimation value regarding the second wireless base station based on a fourth signal received in the same timing as the third signal from the second wireless base station; a calculator that determines, for the first wireless base station, a first correlation value based on a calculation result on the first and second channel estimation values and a calculation result on other channel estimation values having different signal timings, and determines, for the second wireless base station, a second correlation value based on a calculation result on the third and fourth channel estimation values; and a controller that controls the weighting-adding at the equalizer based on the first and second correlation values determined by the calculator.
