Claim One:
1. A wireless communication device, comprising: an antenna configured to receive a wireless signal transmitted from an opposing device; a wireless circuit configured to execute a wireless process for the wireless signal received from the antenna, and to output reception data for which the wireless process is executed; and a reception processing circuit configured to execute a demodulation process for the reception data output from the wireless circuit, and to output the reception data for which the demodulation process is executed, wherein the reception processing circuit includes a weight coefficient computation circuit that prevents reception performance from being degraded by a multi-path, and the weight coefficient computation circuit includes a computation circuit configured to compute a weight coefficient which is used in an equalizer for removing a distortion of a reception signal caused by the multi-path, and which of each of fingers corresponds to each of a specified number of paths among a plurality of paths caused by the multi-path between the opposing device and the wireless communication device, by iteratively performing a computation including a complex multiplication between a weight coefficient while being iteratively computed and a component of a correlation matrix representing a path correlation among the plurality of paths, and a control circuit configured to cause the computation circuit to compute a complex multiplication between a first component of a pair of components which have a complex conjugate relationship and a first weight coefficient while being iteratively computed, and a complex multiplication between a second component of the pair of components which have the complex conjugate relationship and a second weight coefficient while being iteratively computed, when the pair of components which have the complex conjugate relationship is present among components used for computing the weight coefficient of each of the fingers.
