摘要： Logic may estimate a carrier frequency offset. Logic may determine a type of a signal as an Institute of Electrical and Electronic Engineers (IEEE) 802.11p signal, an IEEE 802.11ac signal, or an IEEE 802.11n signal. Logic may select a capture window for capturing a short training sequence of the signal based upon the type of the signal. Logic may determine a coarse frequency offset based upon the short training sequence and the capture window. Logic may select a data processing path for the signal based upon the type of the signal. Logic may determine a fine carrier frequency offset correction based upon a long training sequence of the signal. And logic may update a carrier frequency based on the carrier frequency offset correction.

摘要： Embodiments may comprise logic such as hardware and/or code to reduce power consumption by, e.g., a device such as a station or relay by implementing prediction logic to decode and determine whether a communication affects the operation of the device. Some embodiments may comprise logic to receive at least a portion of a header of a frame from a physical layer and begin to decode the portion of the header of the frame without first checking the correctness of the value in the frame check sequence field. In many embodiments, prediction logic may determine whether the frame could have an impact on the operation of the device. For circumstances in which the prediction logic determines that the frame will not have an impact, the MAC logic may terminate processing, receipt, and decoding of the frame and enter the device into a low power consumption state.

摘要： Pilot logic may determine based upon channel and phase information how to process pilot tones that shift locations every N symbols in an orthogonal frequency division multiplexing (OFDM) packet transmission. Pilot logic may determine a signal-to-noise ratio (SNR) for the channel to determine how to process the shifting pilot tones. Pilot logic may also determine channel and phase information updates such as channel state information and phase correction information from pilot tones. In situations of high SNR, logic may use channel estimates and phase rotations that are obtained from locations of the pilot tones for phase tracking and updating the equalizer. In situations of low SNR, logic may use the phase rotations for phase tracking and not update the equalizer during the OFDM transmission. Logic may also determine the presence or absence of a Doppler effect on the transmission and transmit a selection for N to an access point in response.
