<p>PROBLEM TO BE SOLVED: To prevent the deterioration of error rate caused by a subcarrier not including amplitude fluctuation but including an error due to phase rotation or the like in an orthogonal frequency division multiplexing(OFDM) receiver. SOLUTION: A multiplier 106 multiplies amplitude information of each subcarrier acquired by a synchronization detection section 105 with a received signal and a multiplier 108 multiplies a weighted coefficient outputted from a selector 109 in response to an output of a timing control section 103 in a way that each carrier frequency gets smaller as being apart from a center frequency on a frequency axis.</p> |
