An RSS calculation unit (12) calculates a received signal spectrum on the basis of a CBB signal sent from a frontend (2#b). A CFR estimation unit (13) calculates an estimated transmission path characteristic and a residual signal on the basis of the CBB signal and estimated transmitted symbols estimated by a trellis decoder (8). Further, an NPS estimation unit (14) calculates an estimated noise power spectrum on the basis of the residual signal calculated by the CFR estimation unit (13). A combination unit (4) combines a plurality of received signal spectrums on the basis of the received signal spectrum, estimated transmission path characteristic and estimated noise power spectrum calculated as described above. An equalization unit (5) performs equalization of the combination result, thereby calculating an equalized spectrum. As a result, a receiver of which the frequency selectivity noise resistance property is high can be achieved on a small calculation scale. |
