In certain applications, signal transmit power is adjusted in discrete levels. Moreover, interference powers themselves can be discretely random. For electronic intelligence applications, the authors refer to the signal to be collected as signal of interest (SoI). Thus, for a passive receiver, the resulting instantaneous SoI-to-interference power ratio (SIR) in multiple interferences is a discrete random variable. This means signal detection or collection is not guaranteed. They proposed collection probability (CP) as a metric when the SIR is random. In this study, the authors evaluate CP probabilistically and show CP against SIR threshold degradation and/or improvement as a function of increasing number of interferences, increasing signal power range and increasing distribution gain.
