Abstract
Methods and systems for hardware-efficient carrier sensing are disclosed. The method may include receiving a received signal during a detection window, generating a phase-discriminated waveform based on the received signal, determining a plurality of absolute values respectively based on a plurality of correlations of the phase-discriminated waveform, and generating a detection metric based on a peak value of the plurality of absolute values.
