摘要We consider efficient communications over the multiple-input multiple-output (MIMO) multiway relay channel (mRC) with full data exchange, where each user, equipped with multiple antennas, broadcasts its message to all the other users via the help of a multi-antenna relay. We propose a lattice-precoding based nested lattice coding scheme for the considered MIMO mRC, and derive the achievable rates of the proposed scheme. The proposed scheme is generally applicable to MIMO mRCs with an arbitrary number of users. Particularly, we show that the proposed scheme achieves the asymptotic capacity of the MIMO mRC with two users (i. e., the MIMO two-way relay channel), as the signal-to-noise ratio tends to infinity. We also show that, for a general MIMO mRC, the proposed scheme achieves the capacity of the downlink, and performs close to the cut-set bound of the uplink.
