Carrier frequency offset compensation

Abstract

Technologies directed to carrier frequency offset (CFO) compensation is described. An input buffer receives a first set of incoming samples associated with a first frequency from an incoming data stream. A first outgoing sample of an outgoing data stream is generated using the first set of incoming samples. The first outgoing sample is associated with a second frequency. A ratio between the first and second frequencies is used to determine that the first outgoing sample is associated with a misalignment between the incoming data stream and the outgoing data stream. The input buffer receives a second set of incoming samples associated with the first frequency from the incoming data stream. A second outgoing sample of the outgoing data stream is generated using the second set of incoming samples. The second outgoing sample is associated with the second frequency. The first outgoing sample is overwritten by the second outgoing sample.
