EMC analysis of communication systems under influence of multipoint interference

This paper proposes a new approach for EMC analysis of communication systems, which are affected by a “multitude” of interference. In the communication systems, such as: rural telephone network, satellite module, PSTN equipment and other, their stages are distributed in space. In all the systems each stage is affected by various interference sources with different physical nature (atmospheric discharges, man-made noise radiated and conducted). The interference sources are determined and relation between frequency time domain properties, as well as possible routes or the points possible to be affected. Multitude interference analysis can be applied to different systems such as FDMA and TDMA
