<p>The disclosed digital signal receiver device, which performs doppler-shift compensation with few calculations and has greater reception sensitivity by combining components that leaked into adjacent carriers, has: a transmission line estimating means (1); an FFT computation means (2); a compensation means (3) that compensates for distortion of signals in a frequency region; a leakage factor calculation means (4) that calculates a leakage factor; an interfering component estimation means (5) that estimates an interfering component included in a demodulated carrier on the basis of a signal indicating the leakage factor and signals in the frequency region after compensation; a subtraction means (8) that subtracts the interfering component from signals in the frequency region; interfering component estimation means (6, 7) that estimate a desired second signal component contained in a plurality of carriers aside from the demodulated carrier; subtraction means (9, 10) that subtract the interfering components estimated by the interfering component estimation means (6, 7) from signals in the frequency region; and a combining means (11) that combines the output of the subtraction means (8), and the output of the subtraction means (9, 10).</p> |
