Abstract

Det utføres en dataestimering basert på et glidende vindu. En feil introduseres i dataestimeringen på grunn av kommunikasjonsmodellen som modellerer forholdet mellom de utsendte og mottatte signaler. For å kompensere for en feil i de estimerte dataene, brukes de dataene som ble estimert i et forutgående vindusglidningstrinn (58) eller ledd som ellers ville ha blitt avkortet som støy. Disse teknikkene (50, 52, 54, 56, 58, 60, 62 og 64) muliggjør avkorting av dataene forut for videre prosessering som reduserer vinduets data.
