Disclosed are a distortion-correcting receiver and a distortion correction method capable of precisely cancelling inter-modulation secondary distortion even when an input signal is markedly band-limited in a reception processing unit. In the distortion-correcting receiver (100), the reception processing unit (110) executes reception processing of the input signal and outputs a received signal. A replica signal generation unit (120) generates a replica signal of the inter-modulation distortion component of the input signal by use of the input signal. A correction signal generation unit (130) comprises a frequency property imparting unit (131) and a weighting unit (132), adjusts the frequency property and the gain of the replica signal, and generates a correction signal. A correction signal injection unit (140) adds the reverse-phase signal of the correction signal to the received signal to correct the received signal. |
