A digital rotating complex phasor generator (60) provides a constant magnitude continuous phase signal at either a positive or a negative frequency for translating the frequencies of a modulated signal from a near-zero intermediate frequency (IF) to baseband. The rotating complex phasor generator allows a digital receiver front-end to down-convert the received signal to an IF of substantially zero Hertz prior to analog to digital conversion, even in the presence of large Doppler frequency shifts and tuning uncertainties which may result in a residual IF carrier which has either a positive or a negative frequency.
