Abstract
Interference between communication systems is a critical issue that can impact performance and operability of devices. A wide range of methods and testbeds have been developed to study susceptibility to interference, and each of these testbeds and their experimental test schedules can have different factors and responses. Although there is a variety in testbed design and measurement, it is common to chose a response that is assumed to vary with signal-to-noise ratio. A fundamental issue in any interference study of this type is the assignment of the power of the interference signal in a way that represents the desired environmental situation. This can be a challenging task for signals with disparate time, frequency and powers dynamics. In particular, whether to assign a maximum (peak power) or a time averaged power becomes ambiguous for inter-interference signal comparisons. To address this problem we propose a quantitative scale based on the impact on the receiver of interest. We demonstrate how to form an interference signal agnostic scale and apply that scale for different interference situations. This scale, impact equivalent power ratio, can be transformed into an impact equivalent power with knowledge of the effective noise figure of the system under test.Proceedings Title
