Abstract
The recognition of a frame synchronization pattern or unique word of a received signal may be enhanced using a data-aided estimator of the signal-to-noise ratio (SNR) together with a correlation detector of the unique word to be received. Detecting a frame synchronization pattern or a unique word in a received signal, the SNR is estimated on the received signal with a data-aided SNR estimator using the unique word to be received. If the estimated SNR exceeds a certain threshold, an eventual recognition of the unique word established by a correlation correlator of the receiver is considered reliable. Comparing the SNR with the threshold may be carried out either before or after the correlator has processed the unique word.
