PROBLEM TO BE SOLVED: To provide a frequency division multiplexing transmission signal receiving apparatus capable of being optimized to different delay profiles in accordance with a determination using a combination of a plurality of variation detections, thereby enhancing an error correction capability. SOLUTION: The frequency division multiplexing transmission signal receiving apparatus for receiving a frequency division multiplexing transmission signal using a plurality of carriers includes: an estimation unit 3-1 for estimating a transfer function of a reception signal converted into a frequency domain; a demodulation unit 3 for demodulating the reception signal in accordance with the transfer function estimated by the estimation unit 3-1; variation detection units 5, 5b using a plurality of different variation detection methods on the basis of the transfer function estimated by the estimation unit 3-1; a reliability determination unit 4 for determining reliability in accordance with a result of combining results of the plurality of variation detection units 5, 5b; and an error correction unit 7 for performing error correction on a demodulation signal from the demodulation unit 3 to which a result of the reliability determination unit 4 has been applied.
