Traffic properties of the system with VAMOS possibility (probability of unsuccessful pairing of connections in one timeslot and loss probability due to lack of idle channels) are determined. It is found dependence of these properties on the allowable power difference for successful pairing, on offered traffic and on environmental attenuation coefficient. The serving quality of this channel group is compared to an Erlang group with the same parameters. It is proved that probability of bad serving in the group of VAMOS channels is higher than in Erlang group with the same parameters, but not more than two times. The results obtained by calculation are proved comparing them to the results of simulation. 2018 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64358742007 https://www.redalyc.org/journal/643/64358742007/ https://www.redalyc.org/journal/643/64358742007/html/ https://www.redalyc.org/journal/643/64358742007/64358742007.epub https://www.redalyc.org/journal/643/64358742007/movil 10.15446/ing.investig.v38n3.67523 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.3 Vol.38 |
