I’ve uploaded a report we wrote to intuitively explain why a free distance of two is a necessary condition for supporting iterative decoding convergence to an infinitesimally low probability of error. This is relevant to Variable Length Error Correction (VLEC) codes, Variable Length Codes (VLCs), Reversible Variable Length Codes (RVLCs) and Fixed Length Codes (FLCs). This relates to the EXtrinsic Information Transfer (EXIT) chart analysis of iterative decoding convergence in concatenated codes.
