This paper is concerned with the problem of multiuser precoding design for multiple-output multiple-input (MIMO) two-way relay transmission. In the literature, most of existing studies on multiuser transmission over two-way relay channels have assumed that user terminals (i.e., source nodes) are equipped with a single antenna. To increase the capacity of the multiuser two-way relay network, this paper introduces precoding designs at source and relay nodes for space division multiple access (SDMA) transmissions between source nodes. Numerical simulation results show that the proposed precoding designs at multi-antenna source nodes (i.e., user terminals) can improve the capacity of the network. © 2013 IEEE.

Abstract
This paper is concerned with the problem of multiuser precoding design for multiple-output multiple-input (MIMO) two-way relay transmission. In the literature, most of existing studies on multiuser transmission over two-way relay channels have assumed that user terminals (i.e., source nodes) are equipped with a single antenna. To increase the capacity of the multiuser two-way relay network, this paper introduces precoding designs at source and relay nodes for space division multiple access (SDMA) transmissions between source nodes. Numerical simulation results show that the proposed precoding designs at multi-antenna source nodes (i.e., user terminals) can improve the capacity of the network. © 2013 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
