Summary
Modern communication systems are designed to adaptively operate in complex, time-varying radio frequency (RF) environments. However, current state-of-the art methods for assessing interference susceptibility in controlled laboratory settings rely on overly simplistic inference signals and steady-state equilibrium responses that may not adequately reflect real-world use cases. With the goal of moving beyond traditional steady-state test methods, this project seeks to develop new approaches to assess interference susceptibility of closed-box, commercial off-the-shelf (COTS) communication systems in complex, dynamic spectrum environments. The work will advance measurement science for interference testing to assist spectrum policy decision making and spectrum sharing technology deployment.
Description
The primary project objective is to develop new methods for experimental characterization of dynamic interference impacts on adaptive, closed-box COTS communication links. Specific goals include:
- Dissemination of low-cost, general-purpose testbed designs for interference testing.
- Methods to assess time-sensitive and directional susceptibilities in link performance.
- Metrics for evaluating and comparing interference impacts across different COTS devices in different operating environments.
- Identification of representative classes of synthetic interference waveforms and methods and comparison to impacts from real-world recordings.
