A General Framework of Precoding Design for Multiple Two-Way Relaying Communications

Multiple two-way relaying communications has recently attracted considerable attention due to its various applications in sensor networks, telecommunication systems, home networking, etc. Compared to the classical two-way relaying channel,, multiple two-way relaying is more challenging due to the strong co-channel interference, whereby a message dedicated for one user could cause interference to the others. In this paper, a general precoding design scheme for multiple two-way relaying scenarios is proposed, for which several schemes can be viewed as its special cases. The diversity order achieved by such a transmission protocol is analyzed, and computer simulations are also provided to demonstrate the performance of the proposed transmission scheme.
