A receiver tunable to a plurality of frequency channels includes a reference frequency generator, a downconverter, an analog-to-digital converter, and a processor. The reference frequency generator generates a reference frequency signal, and the downconverter downconverts received signals to provide intermediate frequency signals. Moreover, the downconverter is synchronized to the reference frequency signal. The analog-to-digital converter generates a plurality of complex numbers representative of the received signals including interference components responsive to the intermediate frequency signals wherein the analog-to-digital converter is synchronized to the reference frequency signal. The processor estimates an origin point for the plurality of complex numbers and subtracts the origin point from each of the complex numbers thereby producing interference-compensated complex numbers representative of the received signals with reduced internally generated interference. Moreover, the processor processes the interference-compensated complex numbers to obtain desired signaling information. Related methods are also discussed. |
