二进制多路中继信道的最优编码策略

An Optimal Coding Strategy for the Binary Multi-Way Relay Channel

Lawrence Ong, Sarah J. Johnson, Christopher M. Kellett

摘要:

我们推导了二进制多路中继信道的容量,在该信道中,多个用户通过中继以共同的速率交换消息。容量是通过一种新的函数解码前向编码策略来实现的。在功能-解码-前向编码策略中,中继解码用户消息的功能而不需要解码单个消息。要由中继器解码的功能被定义为使得当中继器将功能广播回用户时,每个用户能够解码所有其他用户的消息。

英文摘要:

We derive the capacity of the binary multi-way relay channel, in which multiple users exchange messages at a common rate through a relay. The capacity is achieved using a novel functional-decode-forward coding strategy. In the functional-decode-forward coding strategy, the relay decodes functions of the users' messages without needing to decode individual messages. The functions to be decoded by the relay are defined such that when the relay broadcasts the functions back to the users, every user is able to decode the messages of all other users.
