| Abstract(in English) | This paper proposes a physical-layer network coding for MIMO two-way two-hop networks that achieves high speed communication independent of the number of antennas on the relay. Especially show a configuration method for the case where the number of antennas of the relay is less than that of the terminal. In other words, high speed communication is achieved by spatial multiplexing over the number of antennas of the relay. Therefore, in the proposed method, precoding is performed not only at the time of terminal transmission but also at the time of relay transmission. In order to achieve high quality spatial multiplexing with the number of terminal antennas, I propose a new non-linear precoding using lattice reduction. In addition, I propose a new precoding method for broadcasting from a relay to two terminals. The characteristics of the proposed method were evaluated by computer simulation, and good performance was obtained even under overload conditions of 4 terminal antennas and 2 relay antennas. |
