Application of the spatial division multiplexing technique in cooperative mimo systems

Abstract

Cooperative MIMO is a combination technique between the single antenna cooperation communications and multiple-input multiple-output systems to achieve the advantages of traditional MIMO. In this paper, we focus on model that combines the spatial multiplexing technique and the cooperative communications, with relay nodes using decode and forward technique where source node and the relay nodes have only one antenna, destination node has multiple antennas; and relay nodes use amplify and forward technique to reduce power consumption and suitable for compact devices; and destination node uses zero forcing (ZF) algorithm. Finally, we show our simulation results in applying the spatial division multiplexing technique in cooperative mimo systems.
