Abstract

I et tidsdelt dupleks (TDD) system er det angitt en pålitelig initialiseringsplan som er anvendbar på en automatisk forsterkningskontroller (AGC) i en basestasjon som er implementert i forskjellige former avhengig av tilgjengeligheten av visse informasjoner slik som signal til interferensforhold (SIR), spredefaktorer og andre parametere. Et mer nøyaktig estimat av det initiale kontrollordet til en forsterkningsjusterbar forsterker for en eller flere tidsvinduer er implementert. Planen er anvendbar på AGC initialisering for hvert tidsvindu i TDD systemet, men er også anvendbar på andre systemer med sending uten begrensning.
