Resistance of the radio modems against the narrow band interference

Abstract

This electronic document is aimed at the influence of interference signals on a communication link. The theory was tested on a real system. The communication link was realized by radio modems RipEx. These modems are optimal devices for the realization of the experiment because they can use different settings for every modulation. One of four modulations can be chosen for the creation of the wireless PC network between the moving systems in these radio modems. The tests were realized for all possible modulations and different channel bandwidths. The modulations used were based on frequency shift keying and quadrature amplitude modulation. The results from the comparison are described in the conclusion.
