  • Patent number: 9461855
    Abstract: 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.

  • Patent number: 9450641
    Abstract: An all-digital spread spectrum clock generating circuit with EMI reduction effect and a method for controlling the same utilize a digital spread-spectrum clock controlling unit to control a digital controlled oscillator, so that it can directly modulates an output clock frequency. Accordingly, the spectrum of the output clock frequency is spread, and the EMI effect due to the output clock signal is reduced. A spread-spectrum clock controller receives a reference clock counting signal and a dividing clock counting signal generated by a frequency detecting unit. After detecting and judging, the spread-spectrum clock controlling unit modulates and maintains a central frequency of the spread-spectrum clock periodically according to the two counting signals, thereby keeping a stability of the central frequency of the spread-spectrum clock signal and decreasing the complexity of the circuit design.
