Abstract
An electronic device that performs an inverse fast Fourier transform (IFFT) on N (N is an integer equal to or larger than 2) orthogonal frequency-division multiplexed (OFDM) transmission signals; performs a fast Fourier transform (FFT) on the N transmission signals which have been subjected to the IFFT; detects phases of the N transmission signals which have been subjected to the FFT; detects relative delay amounts of the N transmission signals based on the detected phases of the N transmission signals; and adjusts a timing at which at least one of the N transmission signals is subjected to the inverse fast Fourier transform based on the detected relative delay amounts.
