论文摘要
为离散的无内存广播频道提供了一个通用的内部界限，并具有任意数量的用户和一般消息集，该设置是一个最通用的并发组播放形式的设置，并旨在为任何一组接收器子集提供消息。可实现性基于叠加编码和分类速率分解和分类，每个接收器共同解码其所需的消息以及通过速率分类分配给其的部分干扰。可实现的证明是基于作者最近针对多访问通道开发的叠加编码的技术，其中包含一般信息，以及新的递归相互覆盖的引理，以分析与BINNING进行更通用的可实现方案。
A general inner bound is given for the discrete memoryless broadcast channel with an arbitrary number of users and general message sets, a setting that accounts for the most general form of concurrent groupcasting, with messages intended for any set of subsets of receivers. Achievability is based on superposition coding and rate-splitting without and with binning, where each receiver jointly decodes both its desired messages as well as the partial interference assigned to it via rate-splitting. The proof of achievability builds on the techniques for the description and analysis of superposition coding recently developed by the authors for the multiple-access channel with general messages as well as a new recursive mutual covering lemma for the analysis of the more general achievable scheme with binning.
