Performance analysis and power optimization for FH secure communication under frequency and phase mismatch
The artificial noise (AN) shielded frequency hopping (FH) secure communication can counteract electromagnetic interference and wiretapping, but its carrier frequencies change rapidly within a wide bandwidth which will raise the level of carrier frequency offset and phase noise, yielding AN cancellat...

description | The artificial noise (AN) shielded frequency hopping (FH) secure communication can counteract electromagnetic interference and wiretapping, but its carrier frequencies change rapidly within a wide bandwidth which will raise the level of carrier frequency offset and phase noise, yielding AN cancellation performance degradation.To tackle this, the signal distortion caused by frequency and phase mismatch (FPM) was mathematically modeled, the AN cancellation performance was evaluated via signal-to-noise ratio, and the system secrecy was scaled via secrecy capacity.On basis of this, the optimal power allocation scheme for AN and confidential signal was designed, and the scheme was expanded according to the FPM level and the propagation channel quality.Numerical simulations verify that FPM can significantly degrade the noise cancellation performance and system secrecy, and to counteract this, the power ratio of AN to confidential signals should decrease with an increasing FPM. |
