Abstract
A global navigation satellite system (GNSS) receiver includes at least one GNSS antenna configured to receive input signaling from at least a first GNSS source and a second GNSS source; an in-phase/quadrature (I/Q) mixer coupled to the at least one GNSS antenna and configured to process the input signaling to obtain complex intermediate signaling; a first complex filter coupled to the I/Q mixer and configured to filter the complex intermediate signaling with respect to a first frequency range to obtain first real output signaling; a second complex filter coupled to the I/Q mixer and configured to filter the complex intermediate signaling with respect to a second frequency range to obtain second real output signaling; and a signal combiner coupled to the first and second complex filters and configured to generate combined real output signaling by combining the first real output signaling and the second real output signaling.
