Abstract
A method includes receiving a signal in a frequency band, which is assignable at least to a communication protocol in which Cyclic Prefixes (CP) are added to symbols having a predefined symbol interval. Multiple autocorrelations of the received signal are computed with a fixed time offset that depends on the symbol interval defined in the communication protocol, and the multiple autocorrelations are accumulated to produce a cumulative autocorrelation. An identification is made, based on the cumulative autocorrelation, whether the received signal is formatted in accordance with the communication protocol.
