ABSTRACT:
In a wireless device, a method and system for a baseband receiver interface including analog and digital components are provided. An analog or a digital interface may be selected for a I/Q data signal received from a front-end receiver. The analog interface may be a conventional RF or a VLIF interface. The I/Q data signal may be digitized when received from the analog interface and saturation detection may be used during digitization of the I/Q data signal. When the analog interface is the VLIF interface, a derotator may be used to remove the VLIF frequency. The derotator may be based on a CORDIC algorithm. The I/Q data signal may be converted from serial to parallel format when received from the digital interface. The received I/Q data signal may be decimated before transferred to a baseband processor.
