Abstract
A symbol phase difference compensating portion () calculates a first phase difference which is a phase difference between a known pattern extracted from a received signal and a true value of the known pattern and performs phase compensation for the received signal based on the first phase difference. A tentative determination portion () tentatively determines an output signal of the symbol phase difference compensating portion () to acquire an estimated value of a phase. A first phase difference acquiring portion () acquires a second phase difference which is a phase difference between a phase of the output signal and the estimated value of the phase acquired by the tentative determination portion (). A first phase difference compensating portion () performs phase compensation for the output signal based on the second phase difference.
