Analysis and design of channel interleavers for terrestrial broadcast

In terrestrial broadcast standards such as DVB-T2, channel interleaving is achieved through stacking several specific interleavers. Therefore, no global optimization is performed and bad interactions between the different interleavers sometimes occur. The aim of this study is to propose design criteria for channel interleavers based on span properties in the time and frequency domains and on the distribution of mutual information (MI).
