The maximum impulsiveness correction factor for Middleton's Class A interference for different modulation schemes

摘要

Simplified algorithms used to determine the performance of digital radio communication systems is desirable. Such simplified algorithms can for example be used in telecommunication performance analysis tools and in frequency measurements to study the impact from disturbances and interference from other users in the dynamic spectrum access (DSA) applications. Today, existing methods are relatively complicated and time-consuming when performance is calculated for interference environments with impulse-rich character. A correction factor (impulsiveness correction factor, ICF) has previously been proposed which opens up for simplified approximations in performance calculations. Using the correction factor in the so-called Gaussian approximation of interference signal provides that simple performance formulas can be used. In this work, the correction factor has been derived for a wider group of interference signals and radio systems which means that its usefulness in practical solutions has increased significantly.
