Abstract
The signal-to-noise ratio (SNR) required for the identification of phase-shift keyed (PSK) signals with a given quality in the developed autocorrelation receiver (ACR) for radio frequency (RF) spectrum monitoring has been studied. We have investigated the PSK signals with the laws of phase shifting according to the Barker and Frank codes. In addition, we have investigated the difference between the SNR value required to identify real signals with PSK and the value used to identify signals simulated in MATLAB. The simulation has shown that identifying the PSK with the phase-shifting law by the Frank code requires 0.2 ... 1 dB SNR more than the Barker code. When receiving a mixture of signals with chirp and PSK, signal identification requires providing SNR by 0.7 1.1 dB more than when receiving an only signal with PSK. To identify the recorded signal with PSK, one needs SNR by 1.6 2.5 dB more than detecting simulated signals. The results obtained can be used to assess the sensitivity of the receiving equipment for RF spectrum monitoring and, accordingly, the range of the equipment.
