Abstract: <P>PROBLEM TO BE SOLVED: To provide an equalizer which does not change the values of originally existing scattered pilots (SP) by an interpolation operation, and does not lower a reception characteristic in the case of mobile reception.  <P>SOLUTION: The equalizer is for a digital ground wave broadcasting receiver which receives an OFDM-modulated signal.

A spline interpolation coefficient value table 14 prestores a spline interpolation coefficient value, wherein the temporal direction SPs stored in the memory and a spline interpolation coefficient value at a center position are defined as one, and also the spline interpolation coefficient value at a position ±4n (n is a natural number) from the center position is defined as zero. A convolution arithmetic circuit 13 applies convolution operation to the SPs read from the memory 11 and the spline interpolation coefficient value read from the spline interpolation coefficient value table to obtain an equalizing coefficient which is obtained by interpolation between the temporal direction SPs. Thus, the demodulation output is equalized based on the temporal direction SPs and the equalizing coefficient.  <P>COPYRIGHT: (C)2003,JPO
