Abstract

Fremgangsmåte for differensial faseevaluering av M-mattisekommimikasjonsdata er anvendt hvor data består av N sekvensielle symboler Sri,..rN som har en av M sendte faser. Valgte sekvenser av N-1 elementer som representerer mulige sekvenser med faseforskjeller er evaluert ved å bruke multisymboldifferensialdeteksjon. Ved å bruke ri som referanse for hvert fasedifferensialestimat, blir s ^"' fasedifferensialsekvenser valgt i form (Pa, Psi ,¿¿¿:. PnO for i = 1 til s for å evaluere symbolsettet hvor s er forhåndsbestemt og l<s<M. Hvert sett av s fasedifferensialestimatverdier er valgt basert på å være nærmest i verdi til faktisk sendt fasedifferensialverdi. Disse s fasedifferensialestimatene kan bli bestemt matematisk som de som produserer det maksimale resultatet ved å bruke konvensjonell differensial deteksjon.
