1. A receiver, comprising:
an radio-frequency (RF) circuit, configured to receive a first satellite signal and a second satellite signal to generate a first base-band signal and a second base-band signal, respectively,
a correlator, configured to use a first local signal to integrate with the first base-band signal to generate a first correlation result, and to use a second local signal to integrate with the second base-band signal to generate a second correlation result;
a signal delay estimator, coupled to the correlator, configured to use the second correlation result to compensate the first correlation result to generate a compensated first correlation result, and determine a signal delay of the first satellite signal according to the compensated first correlation result.
