摘要：
In an equalizer arranged in a wireless communication device: information on correlation in one or more first wireless signals is generated; a channel vector is generated on the basis of the one or more first wireless signals; an extended correlation matrix which contains a correlation matrix indicating the information on correlation and is extended so as to become a circulant matrix is generated; an extended channel vector is generated by extending the channel vector so that the extended channel vector contains elements of the channel vector and has rows the number of which is identical to the number of rows of the extended correlation matrix; and weight coefficients are calculated as a solution, in the frequency domain, of an equation expressed by the extended correlation matrix and the extended channel vector, where the solution is obtained by solving the equation.
