telephony, various types of systems of mobile telephone communication. SUBSTANCE: network considered for multiplexing includes base stations, each having three cells with directions mutually divided through 120 deg, at least four different side stations with mutually different sets of frequencies in cells. Base stations have different sets of frequencies and are arranged in the form of periodically repeated structure, so called frequency structure 4/12. Multiplexing is realized by forcing central base station which has first set G of frequencies and is positioned in the form of rhomboidal structure to replace its set of frequencies with same set R of frequencies possessed by base stations located in angles of rhomboidal structure, by positioning additional base stations inside boundaries of rhomboidal structure and by selection of sets of frequencies for corresponding additional base stations so that frequency or frequencies of their cells were different from frequency or frequencies of cells of nearest base stations. EFFECT: increased carrying capacity of mobile telephone communication system under conditions of noise effect. 6 cl, 3 dwg |
