System and method of detecting end of synchronization header of modulated signals

A receiver of a modulated signal, the receiver comprising:

• a synchronization detector configured to receive a signal indicative of the modulated signal, the modulated signal including a synchronization header and a data payload, and to detect an end of the synchronization header in the signal, wherein the synchronization detector is configured to:
• generate a differential signal based on the signal,
• perform cross-correlation of the differential signal with a reference differential signal to generate a cross-correlation output,
• compare a first sample of the cross-correlation output at a sample index associated with a hypothesized start frame delimiter (SFD) peak index with a second sample of the cross-correlation output at a sample index associated with a hypothesized preamble peak index, and
• detect an end of the synchronization header in response to a comparison result in which a magnitude of the first sample of the cross-correlation output is greater than a magnitude of the second sample of the cross-correlation output.
