Abstract:
A receiver of a GNSS system is provided. The receiver comprises two mixers and a processing circuit. The first mixer down-converts an input radio-frequency signal comprising a first GNSS signal and a second GNSS signal into a first low-frequency signal. The second mixer down-converts the input radio-frequency signal into a second low-frequency signal. The processing circuit generates at least one phase-shifted low-frequency signal according to at least the first low-frequency signal, extract signal components of the first GNSS signal by rejecting signal components of the second GNSS signal according to the second low-frequency signal and the at least one phase-shifted low-frequency signal, and extract signal components of the second GNSS signal by rejecting signal components of the first GNSS signal according to the second low-frequency signal and the at least one phase-shifted low-frequency signal. The first and second GNSS signals are situated in different frequency ranges.
