Abstract:
1. An apparatus, comprising: a first sampler to generate a digital oscillator signal based at least in part on an analog oscillator signal; a second sampler to generate a digital baseband signal based at least in part on an analog baseband signal, with the analog baseband signal having been outputted based at least in part on a multicarrier communication signal; and a signal processor, coupled to the first and the second samplers, to generate a phase noise signal by removing a reference signal from the digital oscillator signal and to remove or reduce phase noise from the digital baseband signal based at least in part on the phase noise signal, with the reference signal being based in part on an estimated frequency for the analog oscillator signal, wherein the signal processor includes a reference signal source configured to generate the reference signal and to adjust the reference signal with a carrier frequency offset estimate.
