Abstract
In one implementation, a method comprises: receiving, in a first radio, a radio frequency (RF) signal and processing the RF signal to provide a bit stream to a digital circuit of the first radio; enabling a first correlator of the first radio to detect at least a first portion of a sync word of a wake-up packet of the bit stream, and thereafter enabling a second correlator of the first radio to detect at least a second portion of the sync word; enabling an averager circuit to detect another portion of the sync word; and in response to detection of the sync word, disabling the first and second correlators and maintaining the averager circuit enabled.
