<p>A receiver (302) for a wireless communication device (106) is disclosed. The receiver comprises a plurality of frequency tines (402) coupled to receive an intermediate frequency signal, each frequency tine of the plurality of frequency tines having a pair of NCOs (412, 432); a comb filter (510) coupled to the center frequency tine (504) of the plurality of frequency tines; and a comparator circuit (610) 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 (106) is also disclosed. The method comprises the steps of providing a plurality of frequency tines (402) 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.</p> |
