| Zusammenfassung: | An apparatus used in a wireless network for collision detection. The apparatus comprises a receiver adapted to receive wireless transmission(s) and a processing unit adapted to: identify a plurality of preamble symbols each in one of said plurality of transmission signals, compute a differential frequency shift between frequency shifts of two of said plurality of extracted preamble symbols, and detect a collision based on said differential frequency shift. |
