Abstract
In this paper, we focus on the reliable network coded cooperation design for multi-way relay network (MWRN) with m users and one single relay, in which every user is supposed to exchange data with all the other m - 1 users (full data exchange) by the assistance of the relay. By reformulating the multi-way relaying network in the framework of error control coding, the LDPC based network coded cooperation design issue for MWRNs is presented. On the basis, the requirements, design criteria, and practical design were proposed to demonstrate how to devise reliable network coded cooperation scheme, such that every user is capable of reliably exchanging data with the other m - 1 users. Our analysis shows that the proposed LDPC based network coded cooperation design exhibits powerful error correction capability, especially when compared with the existing schemes. And the overall required number of time slots to accomplish the proposed LDPC based network coded cooperation scheme is 2m.
