OFDM receiver, terrestrial digital receiver and OFDM receiving method

摘要

In an OFDM receiver, one antenna is selected and two moving average integration values (first moving average integration value AI and 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 BI and 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/AOBI/BO” is true, the C/N ratio of the one antenna is judged to be favorable. When the result of the evaluation equation “AI/AOBI/BO” is false, the C/N ratio of the other antenna is judged to be favorable.
