Abstract
In this paper we describe some practical aspects of the design process of good Raptor codes for finite block lengths over arbitrary binary input symmetric channels. In particular we introduce a simple model for the finite-length convergence behavior of the iterative decoding algorithm based on density evolution, and propose a practical design procedure. We report simulation results for some example codes.
