In this letter, we consider a two-way communication system where two source nodes exchange information via multiple relay nodes. The source and relay nodes may have multiple antennas and the compress-and-forward strategy is applied at each relay node. We aim at maximizing the sum-rate of two-way communication. An iterative algorithm is proposed to jointly optimize the source precoding matrices, the compression noise covariance matrices, and the time-sharing factor. Numerical simulation results show a better performance of the proposed algorithm compared with existing techniques.
