Abstract
Oppfinnelsen frembringer en fremgangsmåte for å regulere transmisjonseffekten mellom første og andre stasjoner i et telekommunikasjonsnett med flere synlige satellitter. Fremgangsmåten omfatter sykliske trinn hvor det for hver av de N kanaler reguleres et kommandosignal for et isolert sendeeffektnivå således at når den effekt som den første stasjon sender det første isolerte signal ut med på hver kanal, er kvalitetsnivået for det tilsvarende isolerte andre signal mottatt av den andre stasjon lik et referansekvalitets- nivå. For alle N kanaler reguleres videre kommandosignaler for N kombinerte sende- effektnivåer slik at når de styrer nivåene som den første stasjon sender ut hvert av de N første kombinerte signaler med på de N kanaler, er kvalitetsnivået for det samlede mottatte signal dannet av de N kombinerte andre signaler lik et referansekvalitetsnlvå. Avhengig av om det isolerte kommandosignal som har det minste nivå er slik at dette minste nivå er mindre enn eller større enn et største tolerert, isolert kommandonivå, velges det isolerte kommandosignal for det minste nivå for å styre den effekt som den første stasjon sender et samtalesignal med på den tilhørende kanal, eller de N kombinerte kommandosignaler velges for å styre den effekt som den første stasjon sender vedkommende kombinerte samtalesignaler med på de N kanaler.
