Hildebrandt, G.G.Hildebrandt2022-03-082022-03-082012https://publica.fraunhofer.de/handle/publica/309812Eine Vorrichtung ist ausgebildet, um eine Signaleigenschaft eines empfangenen Signal zu bestimmen, und um ein Alarmsignal auszugeben, falls die Signaleigenschaft des Signals nicht zu einer Menge einer oder mehrerer zulässiger Signaleigenschaften gehört, wobei die Signaleigenschaft eine oder eine Kombination der Folgenden ist: Modulationsart, Symbolrate, zyklostationäres Muster.The device (10) has an antenna for receiving electromagnetic waves, where the device is formed to receive signals (11) that are filtered out at a preprocessing unit. The device is formed to determine signal properties of the received signals and to output an alarm signal (13) when the signal property does not belong to portion of permissible signal properties, where the signal property is or a combination of type of modulation, symbol rate and cyclostationary pattern. The received signal is subjected to a cyclostationary signal analysis to obtain signal property as a result of the analysis. Independent claims are also included for the following: (1) a wireless communication method (2) a computer program comprising instructions to perform a wireless communication method.de621patent102011076143
