<P>PROBLEM TO BE SOLVED: To synchronize with a predetermined signal included in an input signal, and to process the input signal with high accuracy. <P>SOLUTION: An orthogonalized signal generating part 110A reflects a phase of a pilot signal of an angular frequency ω<SB>C</SB>included in an input signal SIA and generates orthogonalized signals PSA<SB>1</SB>, PSA<SB>2</SB>. A phase computing part 120A computes a phase at each time point reflecting a pilot signal PS based on the signals PSA<SB>1</SB>, PSA<SB>2</SB>. A generating part 130 generates an angular frequency reflecting the pilot signal PS based on the computation result. A phase correcting part 140 corrects a frequency characteristic of a phase shift by a filter in the orthogonalized signal generating part 110A based on the angular frequency generated by the generating part 130. <P>COPYRIGHT: (C)2010,JPO&INPIT |
