ABSTRACT:
A receiver for a wireless communication device is disclosed. The receiver comprises a plurality of frequency tines coupled to receive an intermediate frequency signal, each frequency tine of the plurality of frequency tines having a pair of NCOs; a comb filter coupled to the center frequency tine of the plurality of frequency tines; and a comparator circuit coupled to said plurality of frequency tines, the comparator circuit comparing two outputs of the plurality of frequency tines. A method of determining an intermediate frequency in a wireless communication device is also disclosed. The method comprises the steps of providing a plurality of frequency tines for receiving signals at a plurality of different intermediate frequencies; determining an approximate magnitude of a frequency offset from a center frequency; and determining the sign of the frequency offset.
