Code rate and the area under extrinsic information transfer curves
Anatolii Ashikhmin, Gerhard G. Kramer, Stephan ten Brink · 2003
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.
