Comparison of noise immunity of coherent and autocorrelation demodulators of M-PSK signals in a radio channel with a complex interference situation

摘要

The paper presents the noise immunity analysis of coherent and autocorrelation signal demodulators with multiple phase shift keying in the radio channel in the presence of noise, harmonic and retranslated interference using simulation modeling. A comparison of the results is shown. The energy loss of the autocorrelation demodulator is defined and the effect of the noise intensity on the error bit rate value is estimated.
