Abstract :
Extrinsic information transfer (EXIT) charts predict the convergence behavior of iterative decoding and detection schemes. The EXIT analysis is made precise by introducing a model that applies to iterative decoding of parallel concatenated, serially concatenated, and low-density parity-check codes. The model leads to an area property of EXIT charts.
