Abstract:
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 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 a subset of the samples of a first block with a subset of the samples of a second block to produce an output. The circuitry is configured to compare the output to a threshold value to determine whether the signal comprises a data packet.
