This paper deals with design and analysis of fullduplex relay-aided communication system for the general case of multi-relay and multiuser structure assuming that all of source, relay and destination nodes are equipped with multiple antennas. First, the calculation methods of transmit and receive weight vectors are considered based on zero forcing approach which achieves the cancellation of all the interferences with reduced number of antenna elements. Then computer simulations are carried out

The results show that the proposed system has better performance compared with relay-less and halfduplex relay-aided cases under certain conditions, and some natures of full-duplex relaying including its disadvantages are also investigated. Index Terms-Relay, full-duplex, MIMO (multiple input multiple output), cooperative communication, zero forcing.
