Design of uep-raptor codes over bec
WebThe proposed codes (UEP-LT and UEPRaptor codes) are analyzed for the best possible performance over the binary erasure channel (BEC) in finite-length cases. We derive … WebDec 16, 2015 · In multimedia communications and different other areas, it is desired that channel codes can provide the property of unequal error protection (UEP). In this paper, we study two methods to provide UEP Raptor codes on the binary erasure channel (BEC): (1) Using UEP precode (2) Using UEP LT codes.
