Abstract

Turbo codes have achieved near Shannon limit performance in data communication over noisy channels. Recently introduced Extrinsic Information Transfer (EXIT) Charts [1] have become an essential part of turbo code design and have also been used as a complementary design tool for the traditional bit error rate simulations. Additionally, compressive turbo codes have been shown to achieve near-entropy performance in different source coding problems [2], [3], [4]. The main objective of this paper is an extension of EXIT charts from turbo channel codes to turbo source codes, as well as extension of this technique to analog and finite precision iterative decoders.
