Detection of repetitive data signals

There is provided an apparatus for detecting repetitive information in data packets communicated between a first node and a second node over a wireless network. The apparatus includes a processing circuitry. The processing circuitry is configured to: (a) collect samples of a data communication signal transmitted between said first node and the second node over said wireless network at a plurality of respective times; (b) group the collected samples into a plurality of sequences of samples; (c) combine the sequences of samples into at least one united signal; and (d) based on an analysis of the at least one united signal, provide a signal indicative of repetitive information in a plurality of data packets carried by said data communication signal.
