<p>In a receiving apparatus having a function of removing interference signal components, a good interference removing effect can be ensured, while achieving a reduction of a processing time required for estimating the transmission path of the interference signals or achieving a reduction of the processing amount (scale) required therefor. A receiving apparatus comprises an analog signal processing part that converts an analog signal, which has been obtained by down-converting a received signal, to a digital signal; and a digital signal demodulating part that demodulates the digital signal from the analog signal processing part. A desired signal parameter estimating part (202) of the digital signal demodulating part comprises a desired signal transmission path estimating part (303) that outputs a transmission path estimation value of a desired signal as one of predetermined parameters related to the desired signal; a replica generating part (302) that generates, based on both the transmission path estimation value of the desired signal and a known signal, a replica signal of the desired signal; and a replica subtracting part (301) that outputs, as a desired signal replica removal signal, a subtraction output obtained by subtracting the replica signal of the desired signal from the received signal.</p> |
