Abstract
A signal acquiring unit () performs signal detection and initial synchronization on an output from a RF frontend () by performing circular convolution operation using a first code replica corresponding to a case where a ranging code does not change in polarity and a second code replica corresponding to a case where a ranging code changes in polarity. A signal tracking unit () performs synchronization tracking using a result of signal acquisition output from the signal acquiring unit () as an initial value.
