Abstract

A communication apparatus comprises an inserter that inserts an element having a value of 0 or nearly 0 into a predetermined position of a modulated signal to generate inserted data; an operator that adds a pilot signal comprising a data series of which the elements at the positions corresponding to the predetermined positions in the modulated signal are multiplied by a first amplitude coefficient and the elements other than the elements multiplied by the first amplitude coefficient are multiplied by a second amplitude coefficient to the inserted data to generate a post-operation data; an IFFT unit that performs IFFT on the post-operation data; and a transmitter that generates a baseband signal based on the post-operation data on which the IFFT is performed and transmits a transmission signal generated from the baseband signal.
