Abstract:
1. An apparatus for wireless communication, comprising: a correlation circuit configured to correlate a received waveform with a target waveform, the correlation circuit further configured to compare a result of the correlation to a threshold and output a first signal when the result of the correlation exceeds the threshold; a demodulation circuit configured to generate a sequence of bits by demodulating at least a portion of the received waveform in response to receiving the first signal; a comparison circuit configured to compare, in parallel, a plurality of circularly rotated versions of a target sequence of bits with the demodulated sequence of bits; and a trigger detection circuit configured 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.
