摘要

PROBLEM TO BE SOLVED: To correct properly a code phase error when a reception signal is a multipath signal without increasing an operation amount, or without enlarging a circuit scale.;SOLUTION: A PE value which is a ratio between a correlation value of a Punctual phase and a correlation value of a phase advanced as much as N (0N1) chip from the Punctual phase is calculated based on a correlation operation result to the reception signal. The PE value has a relation wherein both a code phase (Punctual phase) being tracked at present and en error ERR of an actual peak phase have an approximately coincident increasing/decreasing direction relative to elapse of time. Hereby, when determined that the reception signal is a multipath signal, the error ERR is calculated based on the PE value, and the Punctual phase is corrected by using the calculated error ERR.;COPYRIGHT: (C)2009,JPO&INPIT
