Description
Summary:The resistance of different types of digital radio signals to certain interferences and jamming signals is essential from military point of view. An experimental method was chosen to take into consideration influence of all factors and elements to achieve more accurate results. This paper presents results of experiments concerning influence of intentional jamming on digital FSK and PSK demodulators. Several types of noise and imitating signals are considered including autoregressive models of the jammed signal. The demodulators are software DSP demodulators working in real time.
