A Novel Method to Evaluate the Effectiveness of Communications Jamming

This paper presents a novel method to evaluate communications jamming effectiveness by using amplitude probability distribution (APD). Average crossing rate (ACR) and power spectral distribution (PSD). The three parameters give information about amplitude domain, time domain and frequency domain of a jamming signal, respectively. In earlier papers the APD parameters has been considered individually to analyze the performance degradation of communications. However, since the three parameters can give more detailed description of a jamming signal, we can connect them together with the performance of digital communications. And then according to the analysis results, we can evaluate communications jamming effectively and generate a jamming signal to accomplish communications jamming. In this paper a PHS system and pulsed sine wave jamming signals are given as an example.
