Abstract
This paper studies the problem of Raptor-code design for binary-input AWGN (BIAWGN) channels using the mean-LLR-EXIT chart approach presented in [1]. We report that there exist situations where such a design approach may fail or fail to produce capacity-achieving codes, for certain ranges of channel SNR. Suggestions and discussions are provided pertaining to the design of Raptor codes for BIAWGN channels using the mean-LLR-EXIT chart.
