FIELD: physics, radio. ^ SUBSTANCE: invention refers to radio communications and is intended for assuring communications electromagnetic compatibility (EMC). In method at least one object with operating at least two electronic facilities (EF) of overlapping coverage areas, e.g., mobile radio systems (MRS), interacting with other EF particularly, if any in overlapping coverage areas, operates at preset working frequency ranges. At the first stage considering power criterion from all set of transmitters, there is identified group of particular transmitters which can simultaneously operate at preset frequency channel from working frequency range and specified transmitted radio signal parameters providing radio coverage of serviced territory, preventing unallowable effect on receivers of others EF. Such identification is performed for each frequency channel from working frequency range, and for each transmitter, there is derived set of frequency channels from this range, each of which can be separately applied on this transmitter to provide MRS operation assuring intersystem EMS. At the second stage from specified set of frequency channels those are chosen for which conditions and criteria providing elimination of potential effect of intermodulation products (IP) are met, and include EF thus operating at frequencies specified with reference to variety of versions, produced by method and not resulting in IP up to the seventh order inclusive both transmission and reception frequencies. ^ EFFECT: communication quality improvement. ^ 6 dwg, 6 tbl |
