<p>The receiving device, which can correct a Doppler shift by a small amount of calculation and can improve receiving sensitivity by combining components leaking into adjacent carriers, includes: a transmission path estimation means (1); an FFT computation means (2); a correction means (3) for correcting distortion of a signal of a frequency domain; a leak-in coefficient calculation means (4) for calculating an inter-carrier interference leak-in coefficient; an interference component estimation means (5) for estimating an interference component included in a carrier to be demodulated on the basis of a signal indicating the leak-in coefficient and a corrected signal of the frequency domain; a subtraction means (8) for subtracting the interference component from the signal of the frequency domain; a signal component estimation means (6, 7) for estimating a desired second signal component included in a plurality of carriers other than the carrier to be demodulated; a subtraction means (9, 10) for subtracting the interference component estimated by the signal component estimation means (6, 7) from the signal of the frequency domain; and a combining means for combining an output from the subtraction means (8) and an output from the subtraction means (9, 10).</p> |
