具有相关源的有限域多路中继信道:三用户情形

The Finite Field Multi-Way Relay Channel with Correlated Sources: The Three-User Case

Lawrence Ong, Roy Timo, Gottfried Lechner, Sarah J. Johnson, Christopher M. Kellett

摘要:

研究了具有相关信源的三用户有限域多路中继信道。这三个用户产生可能相关的消息,并且每个用户将其消息可靠地发送到香农意义上的另外两个用户。由于用户之间没有直接的链路,通信是通过中继进行的,并且从用户到中继的链路和从中继到用户的链路是具有任意分布的加性噪声的有限域加法器信道。问题是确定所有可能的可实现速率的集合,定义为用于可靠通信的每个源符号的信道使用。对于两类信源/信道组合,采用Slepian-Wolf信源编码与函数解码前向信道编码相结合的方法,得到了解。

英文摘要:

The three-user finite field multi-way relay channel with correlated sources is considered. The three users generate possibly correlated messages, and each user is to transmit its message to the two other users reliably in the Shannon sense. As there is no direct link among the users, communication is carried out via a relay, and the link from the users to the relay and those from the relay to the users are finite field adder channels with additive noise of arbitrary distribution. The problem is to determine the set of all possible achievable rates, defined as channel uses per source symbol for reliable communication. For two classes of source/channel combinations, the solution is obtained using Slepian-Wolf source coding combined with functional-decode-forward channel coding.
