论文摘要
我们考虑在多级别3接收器广播渠道的容量区域中达到速率，在该渠道中，第二个接收器相对于第一个接收器而降级，并且消息集退化。我们根据极地代码提出了一种两级链式策略，该策略在没有时间共享的情况下实现了所考虑的设置的容量区域。我们还查看了此问题的略有变化，其中第一个接收器只需要解码其自己的私人消息，而其他两个接收器则需要解码它们共有的另一个私人消息。我们观察到容量区域不会扩大，因此提出的极地编码策略也达到了该问题的容量区域。
We consider achieving the rates in the capacity region of a multi-level 3-receiver broadcast channel, in which the second receiver is degraded with respect to the first receiver, with degraded message sets. We propose a two-level chaining strategy based on polar codes that achieves the capacity region of the considered setting without time-sharing. We also look at a slight variation of this problem, where the first receiver only requires to decode its own private message and the other two receivers require to decode another private message common to them. We observe that the capacity region does not enlarge and so the proposed polar coding strategy achieves the capacity region for this problem as well.
