广播Z信道的最优传输策略和显式容量域

Optimal Transmission Strategy and Explicit Capacity Region for Broadcast Z Channels

Bike Xie, Miguel Griot, Andres I. Vila Casado, Richard D. Wesel

摘要:

本文给出了两用户广播Z信道容量域的显式表达式,并证明了通过对每个用户进行独立编码可以得到最优的容量域。具体地,对应于每个用户的信息消息被独立地编码,并且这两个编码流的OR被发送。非线性涡轮码,提供了一个受控的1和0的分布被用来证明一个低复杂度的计划,接近最佳的边界。

英文摘要:

This paper provides an explicit expression for the capacity region of the two-user broadcast Z channel and proves that the optimal boundary can be achieved by independent encoding of each user. Specifically, the information messages corresponding to each user are encoded independently and the OR of these two encoded streams is transmitted. Nonlinear turbo codes that provide a controlled distribution of ones and zeros are used to demonstrate a low-complexity scheme that operates close to the optimal boundary.
