Abstract
A first calculator generates first computational data by reordering elements in at least one of either a real data sequence or an imaginary data sequence constituting a data sequence having a number of elements determined according to a number of elements in a preamble model. A second calculator generates second computational data in which elements of data obtained by applying a fast Fourier transform to the first computational data are spaced apart by a designated number of elements. A preamble generator generates a preamble by multiplying each element of the second computational data by an element of the preamble model at a same position as the each element. A preamble determiner determines on the preamble as a preamble of the transmit signal in a case in which a peak-to-average power ratio of data obtained by applying an inverse fast Fourier transform to the preamble matches a predetermined criterion.
