<P>PROBLEM TO BE SOLVED: To provide a phase determining apparatus for correctly determining a phase of a known signal even when the effect of white thermal noises or the like is great. <P>SOLUTION: The phase determining apparatus 100 includes: a reception section 10; a partial signal acquisition section 20; a phase correction section 30; and a buffer 40. The reception section 10 receives a signal sequence to which a known signal is periodically inserted and provides an output to the partial signal acquisition section 20. The partial signal acquisition section 20 acquires a prescribed partial signal and partial signals before and after the prescribed partial signal from the signal sequence received by the reception section 10, and writes the acquired signals to the buffer 40. The phase correction section 30 executes the correction of the phase of the prescribed partial signal written in the buffer 40 on the opportunity of receiving a write end notice informed from the partial signal acquisition section 20. <P>COPYRIGHT: (C)2007,JPO&INPIT |
