摘要
Processing of a data packet within a received wireless signal includes determining a frequency modulation ("FM") domain carrier frequency offset ("CFO") estimate component from a plurality of samples of the received wireless signal, determining a phase domain CFO estimate component from the plurality of samples of the received wireless signal, and determining a CFO estimation as a function of the FM domain CFO estimate component and the phase domain CFO estimate component. The data packet may be a Bluetooth Low Energy data packet. The FM domain CFO estimate component and the phase domain CFO estimate component may be determined from samples of a preamble field of the data packet.
