Design of uep-raptor codes over bec
Weba linear time block code, like an LDPC code, Raptor Codes provide marvelous encoding and decoding speeds while providing near optimal performance for the BEC [8]. Raptor codes are an extension of the other part of LT codes combined with a system of pre-coding. The design and degree distribution pre-coding is the heart of Raptor codes.

WebAug 14, 2024 · 3 Design of UEP-Systematic Raptor Code 3.1 Short Intertwined Systematic Raptor Code A scheme is proposed that is named Short Intertwined Systematic Raptor (SISR) codes. A short LT code which with the length of P' is added between systematic symbols and redundant symbols. Webemployed to design UEP-LDPCcodes in [3]. Here, exploiting the finite-length scaling methodology, we introduce a novel approach to analytically evaluate the inherent UEP properties in (finite-length)irregular LDPC codes. It is known that in an irregular LDPC code transmitted over a BEC, variable nodes with larger degrees provide better
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. Webtransmitted symbols. Moreover, Tornado codes can achieve a rate just below the capacity 1 p of the BEC. Thus they are capacity-approaching codes. Tornado codes are closely related to Gallager’s LDPC codes [3], where codes are based on sparse bipartite graphs with a fixed degree dl for left nodes (information symbols) and dr for right
