Abstract
It is possible to provide an SC-FDMA transmission device and an SC-FDMA transmission signal formation method which improve the transmission efficiency of the SC-FDMA transmission signal. The SC-FDMA transmission device () performs the discrete Fourier transform process on a primary modulation signal sequence formed by N primary modulation symbols to obtain a plurality of frequency components, which are respectively mapped onto different subcarriers. The obtained SC-FDMA symbol is subjected to the inverse Fourier transform process before being transmitted. A propagation path information decoding unit () acquires frequency selection characteristic in a propagation path to/from a reception side. A cyclic shift unit () and a correlation characteristic judgment unit () adjust the frequency response of the SC-FDMA symbol according to the frequency selection characteristic. The adjustment is performed by a result of correlation obtained by performing a correlation calculation between the propagation path frequency selection characteristic and the SC-FDMA symbol.
