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 WebDesign of UEP-Raptor codes over BEC. Lei Yuan, Jianping An.
