A kurtosis-based approximative method for intersystem interference analysis

The problem to determine the impact on digital communication systems due to electromagnetic interference often requires complex calculations and analyses. Therefore, there is a need for approximate methods suitable for computer-based tools for intersystem interference analyses. Here we have investigated the impact on a digital radio receiver from different kinds of pulsed interfering signals. We also estimate the kurtosis for these signals, both analytically and through simulations. Furthermore, we propose a low-complexity method that uses the kurtosis measure to estimate the impact from intersystem interference on a digital radio receiver. Such a method can for example be used in a tool for intersystem interference analyses.
