Abstract
Provided is a technology capable of securing communication quality without providing an additional function such as phase correction. A base station device and a communication terminal device when operating as a transmitting device rotate inverse fast Fourier transform (IFFT) output, and copy a last portion of the rotated IFFT output to a head of the rotated IFFT output as a cyclic prefix (CP) to thereby generate a transmission signal so that there is no phase rotation at a head of a demodulation reception window set in a receiving device.
