Simplified algorithms used to determine the performance of digital radio communication systems is desirable. Today, existing methods are relatively complicated and time-consuming when performance is calculated for interference environments with impulse-rich character. There is a need for simplified methods for example in telecommunications conflict analysis tools and the frequency measurements to study the occupancy from disturbances and other users in the dynamic spectrum access (DSA) applications. A correction factor (impulsiveness correction factor (ICF)) has previously been proposed to allow the use of simplified approximations performance calculations. Using the correction factor in the so-called Gaussian approximation of interference signal provides that the simple performance formulas can be used. The correction factor in this work has been developed to cover a wider group of interference signals and radio systems which means that its usefulness in practical solutions has increased significantly. The correction factor are used in the Swedish armed forces new computer-based tool (NTK) for intersystem-interference analysis as well as in FOI's demonstrator tool GENESIS. Furthermore, the correction factor has been published in two different scientific articles. This project was funded by the Swedish defence material administration.
