    Patent number: 6683493
    Abstract: In-phase and orthogonal components of a base band signal having a preamble symbol are squared to obtain squared in-phase orthogonal components. Amount of correlation is obtained between the squared in-phase component and a ½ symbol frequency component output from a VCO or an oscillator, and amount of correlation is obtained between the squared orthogonal component and the ½ symbol frequency component. Finally, a phase control signal for carrying out a phase control is generated by using the obtained amount of correlations.
