Abstract
Systems and apparatus are disclosed for a target device to detect a trigger from an initiating device. One implementation includes a wireless device configured to correlate a received waveform with a target waveform, compare a result of the correlation to a threshold and output a first signal based on the comparison of the result and the threshold. The apparatus may also be configured to generate a sequence of bits by demodulating at least a portion of the received waveform in response to receiving the first signal, to compare in parallel a plurality of circularly rotated versions of a target sequence of bits with the demodulated sequence of bits, and to combine the results of the comparisons and output a second signal when the combined comparisons indicate that the demodulated sequence of bits corresponds to the target sequence of bits.
