A General Framework and Optimization for Spatially-Coupled Serially Concatenated Systems

Abstract : In this paper, we provide a general framework for spatially-coupled concatenated systems. We explicit the analogy with spatially-coupled protographs and provide an adapted EXIT chart analysis. By proposing a continuous-valued coupling matrix, we propose a code design procedure for faster convergence. When considering general bit- interleaved coded-modulation scheme, we also conjecture that the spatially-coupled scheme of general detectors saturates to a value very close (lower bound) to the threshold given by the Area theorem.
