本文的主要目的是将EXIT图性能分析技术从Turbo信道码推广到用于Slepian-Wolf问题的压缩Turbo码。我们提出了在这个问题中使用EXIT图的方法，并说明了几对相关的无记忆源和Turbo压缩方案的结果，观察数值EXIT结果和BER模拟之间的良好匹配。因此，本文提出的广义EXIT图允许预测Slepian-Wolf Turbo压缩的迭代解码过程的行为。
The main objective of this paper is to extend EXIT charts performance analysis technique from turbo channel codes to compressive turbo codes used for the Slepian-Wolf problem. We present the methodology on using EXIT charts in this problem and illustrate its results for several pairs of correlated memoryless sources and turbo compression schemes, observing a good match between numerical EXIT results and BER simulations. Consequently, the generalized EXIT charts presented in this paper allow one to predict behavior of the iterative decoding process for Slepian-Wolf turbo compression.
