ABSTRACT:
In an OFDM receiver, one antenna is selected and two moving average integration values (first moving average integration value AIand second moving average integration value AO) of a non-delay symbol and a delay symbol are calculated. Another antenna is selected and two moving average integration values (first moving average integration value BIand second moving average integration value BO) of a non-delay symbol and a delay symbol are calculated. When a result of an evaluation equation “AI/AO>BI/BO” is true, the C/N ratio of the one antenna is judged to be favorable. When the result of the evaluation equation “AI/AO>BI/BO” is false, the C/N ratio of the other antenna is judged to be favorable.
