Abstract
The communication performance in the presence of man-made interference of a multiple terminal, diversity augmented, vehicular, radio relay communication system dispersed throughout a large geographical area has been studied by a computer modeling of the multinode system. The radio relay system operating at UHF in the presence of unintentionally generated man-made radio noise has been evaluated from the viewpoint of message propagation rate and completeness of coverage for varying relay point distributions. The communication performance for several distributions of mobile relays dispersed in a specified operational area of western Europe was examined under the influence of man-made UHF noise generated by 52 urban industrial centers in the region. The effectiveness of message repetition in overcoming the adverse effect of intense man-made noise was measured as a function of relay point density.
