Abstract :
We study the iterative decoding convergence of parallel concatenated codes (PCC) consisting of three constituent codes. A three-dimensional extension of the extrinsic information transfer (EXIT) chart technique is used to predict convergence thresholds and to visualize the course of the iteration.
