“…Among the numerous two-way relaying protocols, such as amplify-and-forward (AF) and decode-and forward [2], AF protocol gets favored as one or more low-complexity relay nodes are adopted to assist the communication between sources and destinations without decoding the signals.…”

We design a scheme of precoding matrices for two-way multiuser relay systems, where a multiantenna relay station (RS) operating in an amplify-and-forward model simultaneously receives information from all multiple-antenna users. Considering the feasibility in mathematical analysis, users are distributed in two symmetrical groups. To reduce the complexity of proposed precoding scheme, we employ the QR decomposition and complex lattice reduction (CLR) transform to replace the two times singular value decomposition (SVD) of conventional BD-based precoding algorithm by introducing a combined channel inversion to eliminate the multiple users interference (MUI). Simulation and performance analysis demonstrate that the proposed LR-MMSE algorithm has not only a better bit error rate (BER) performance, a higher sum-rate, and simple architecture, but also 89.8% and 35.5% less complexity compared to BD-and MMSE-based scheme.

In the paper, we present a road-map towards a near-capacity large-scale multi-user cooperativecommunications (NLMC) system, where all the evolution paths converge to the construction of the NLMC system. More specifically, we will summarize all relevant schemes appearing on the road-map in the unified frame-work of forward error correction. various network coding design paradigms are highlighted for illustrating how the NLMC systems might be designed for meeting diverse design criteria in the context of cooperative and cognitive communications, where the channel capacity of the NLMC systems is used for comparing the different design paradigms.INDEX TERMS Channel coding, network coding, cooperative communications.
