Abstract:   (235 Views)

In this paper, power efficiency (PE) of a relay interference channel including multiple transmitter nodes, multiple relay nodes and multiple destination is investigated. It is assumed that the destination and transmitter nodes are equipped with a few number of antennas but the relay nodes have a large number of antennas. Amplify-forward and decode-forward schemes by using MRT/MRC and ZF processes are considered. The PE of the system is studied and the effect of the transmitter and relay nodes power on the PE is investigated. It will be shown that by using a large number of antennas at the relay nodes, one can reduce the transmitted power of transmitter nodes without any degradation in the performance. Also, when the relay nodes have a limited number antennas, decode-forward scheme has better performance with respect to amplify-forward scheme. However, by increasing the number of relays antennas they are converge to each other. Finally, it is shown that the decode-forward scheme needs less power for achieving 1 bit/s.
