To provide a radio receiving device receiving radio signals that minimizes the effects of interference. In the radio receiving device, a transfer function unit estimates a frequency domain transfer function and a time domain transfer function based on a pilot symbol that is received by the antenna. A signal-to-interference noise ratio unit calculates a signal-to-interference noise ratio based on the estimated frequency domain transfer function and time domain transfer function for each information element of sequential N information elements that are included in the pilot symbol. A block size selection unit calculates among the N information elements a sequential range P with limited interference effects based on the calculated signal-to-interference noise ratio. A data receiving unit calculates a compensation value based on the value of P and the frequency domain transfer function estimated by the transfer function estimation unit and stores the compensation value, and, when the antenna receives a data symbol, calculates a received symbol consisting of the P infomiation elements based on the received data symbol and the compensation value that is stored in a storage region.
