An Overview on Multiple Antenna Relay Selection in Multiuser network MIMO system

  Saiyed Saifali I.,  J. N. Patel

The use of multi-antenna relays has emerged as a very promising technique for combating fading, enhancing throughput and extending coverage in emerging wireless broadband networks.In practical multi-user multi-relay systems, not all nodes are able (or allowed) to cooperate during data transmission. Selecting subsets of advantageous relays and users simultaneously for cooperation and communication will not only enhance the system performance by leveraging the inherent cooperative and multiuser diversity in the network, but also reduce signaling overhead and complexity. In order to have any practical relevance, user-relay selection and/or association schemes must be of acceptable complexity and fit within a small fraction of the coherence time of the channel. In this paper, we will present a brief literature review on two-hop relaying, full duplex relaying and multiuser network MIMO systems. First, we investigate the major challenges in user and relay selections and further we show various techniques respect to MIMO and Multiuser MIMO system.
