A Study on Digital-Analog Concatenated Coding and Iterative Decoding

在本研究中，数个最新的无线通讯技术被视为三种类型的模块：数位编解码器，类比编解码器，以及无线通道。为了使三重级联系统的性能接近最大值，在互信息方面尽可能地消除了模块间的失配。本研究的一个主要贡献是一种方法，外部信息传输（EXIT）特性起着关键作用，以消除不匹配。

In this research, several cutting-edge wireless communication techniques are regarded as modules which are classified into three types: digital codec, analog codec, and wireless channels. In order to approach the maximum capability of the triple concatenated systems, mismatch among the modules are removed as possible in terms of mutual information. A major contribution of this research is an approach that extrinsic information transfer (EXIT) characteristics plays a key role to remove the mismatch.
