<p>Systems, methods, and devices for detecting packets in signals are described herein. The apparatus comprises a receiver configured to receive a signal comprising a plurality of samples. The apparatus comprises circuitry. The circuitry is configured to apply a match filter (228) to the plurality of samples to produce a plurality of blocks of samples, each block comprising a number of samples. The circuitry is configured to correlate (510a, 510b) a subset (505a, 505b,...) of the samples of a first block with a subset of the samples of a second block (505b, 505c,...) to produce an output. The circuitry is configured to compare (525) the output to a threshold value (T) to determine whether the signal comprises a data packet.</p> |
