Theoretical approach applied to EMC measurements problems

A theoretical approach that uses minimum a priori information of sources parameters, their locations in the space and propagation properties is developed to predict EMI parameters in urban zone, where the communication systems are normally operated. The model is given by an exact and simplified evaluation. The exact evaluation is applied to statistical moments, APD, VD, and LD; the simplification in accordance with the Gamma distribution and conception of average distance is done. As an example, the model is used to predict the interferences level in radio systems for the range frequency VHF/UHF in a zone of Mexico city.
