<P>PROBLEM TO BE SOLVED: To provide an OFDM receiver which operates even under intense fading environment. <P>SOLUTION: A correlating unit 35 calculates correlation between 16-bit data held in a shift register 31 and known data. An adding unit 43 cumulatively adds correlation values of data at the same positions in respective frames. A comparing unit 45 outputs a synchronism establishment signal indicating that frame synchronism is established when a cumulative correlation value exceeds a threshold. <P>COPYRIGHT: (C)2013,JPO&INPIT |
