Abstract
Fremgangsmåte for dataestimering for et tidsdelt dupleks (TDD) kodedelt multippel aksess (CDMA) system eller ethvert annet system som bruker en utvidet algoritme (EA) som preferanse over en trunkert algoritme (TA) blir beskrevet. EA unngår implementeringsfeil ved å velge en korrekt utvidet matrise og aksepterer bruken av et hardwarestykke. EA oppveier også tap av multiple signaler i haledelen av hvert datafelt, og unngår feil på grunn av transformasjon av en Toeplitz matrise til en sirkulerende matrise.
