Abstract
A method to compensate a carrier frequency offset (CFO) in a receiver is disclosed. The method includes receiving discrete time samples, obtaining a sample vector from the received discrete time samples, obtaining tentative CFO estimates based on the sample vector, selecting a CFO having a greatest compensation coefficient from the tentative CFO estimates, and compensating the CFO in the received discrete time samples.
Claims23
A method to compensate a carrier frequency offset (CFO) in a receiver, the method comprising:
- receiving discrete time samples;
- obtaining a sample vector from the received discrete time samples;
- obtaining tentative CFO estimates based on the sample vector, wherein each of the tentative CFO estimates is associated with a compensation coefficient;
- and
- selecting a CFO having a greatest compensation coefficient from the tentative CFO estimates;
- and
- compensating the CFO in the received discrete time samples.
A receiver configured to compensate a carrier frequency offset (CFO), the receiver comprising:
- a processor configured to
- receive discrete time samples and obtain a sample vector from the received discrete time samples;
- obtain tentative CFO estimates based on the sample vector and select a CFO having a greatest compensation coefficient from the tentative CFO estimates, wherein each of the tentative CFO estimates is associated with a compensation coefficient;
- and
- compensate the CFO in the received discrete time samples.
