WebIII.RELATED WORK:UEP FOR FOUNTAIN & RAPTOR CODES A novel scheme of UEP for Raptor family of codes was ﬁrst proposed by Rahnavard et. al. [8]. It is a generic scheme that can be used for any Fountain code. This method was subsequently improved to produce different variations, such as the one proposed in [9]. The UEP is achieved by 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 WebAbstract In this paper, we propose a new scheme to construct Raptor codes that can provide unequal error protection (UEP) and unequal recovery time (URT) properties.
