Abstract
According to an embodiment of the present disclosure, a receiver of modulated signals comprises a signal mixer, a synchronization detector, and a data demodulator. The signal mixer is configured to perform baseband down-conversion of a signal according to a mixer frequency, the signal including a synchronization header and a data payload. 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, and analyze the cross-correlation output to detect an end of the synchronization header. The data demodulator is configured to demodulate the data payload in response to detection of the end of the synchronization header.
