Interference protection criteria simulation

Abstract

Interference protection criteria (IPC) determine the interfering signal power a system can tolerate when sharing spectrum with other services. IPC are typically determined by measurements, but good measurements are often hindered by restrictions on equipment availability and inaccessible equipment signals, performance metrics, and operational parameters. The purpose of the research described in this article is to determine if these difficulties can be avoided by replacing IPC measurements with software simulations. Our approach is to use commercial off-the-shelf (COTS) radio system simulator software to model previous IPC measurement test fixtures and compare simulated to measured results. Measurements of mutual interference between radar and LTE systems are compared. The comparison shows that simulation can be a viable alternative to IPC measurement.
