Abstract
A transmitting apparatus, a receiving apparatus and a wireless communication method for suppressing interference between codes, while further reducing the ratio of redundant components occupying a signal to improve the transmission efficiency. The transmitting apparatus () transmits a signal having a frame structure in which a plurality of symbols follow a pilot symbol to which a guard interval has been added. In the receiving apparatus () that receives that signal, a long FFT target section acquiring part () acquires, from the received OFDM signal, a long FFT target section that is a target section in which delay waves are to be removed by use of a pilot symbol. A long FFT part () performs a fast Fourier transformation of the long FFT target section to convert it to a frequency domain signal. A frequency equalizing part () performs a frequency equalization of the long FFT target section by use of an interpolation result of communication line estimation value. A long IFFT part () performs an inverse fast Fourier transformation of the long FFT target section as frequency equalized to convert it back to a time domain signal.
