Abstract
An apparatus comprises an RF receiver for receiving an RF signal. The RF receiver includes front-end circuitry to generate a first down-converted signal, and a plurality of signal detectors to generate a corresponding plurality of detection signals from signals derived from the down-converted signal. The RF receiver further includes a controller to provide at least one control signal to the front-end circuitry based on the plurality of detection signals.
Claims20
An apparatus comprising:
- a radio-frequency (RF) receiver for receiving an RF signal, the RF receiver comprising:
- front-end circuitry to generate a down-converted signal;
- a plurality of signal detectors to generate from the down-converted signal a plurality of detection signals and a plurality of frequency offset estimates;
- at least one compensation circuit to compensate for frequency offset;
- and
- a controller to provide at least one frequency offset estimate in the plurality of frequency offset estimates to the at least one compensation circuit based on the plurality of detection signals.
