Opportunistic relay selection in multicast relay networks using compressive sensing [PDF]
2014 IEEE Global Communications Conference, 2014 Relay selection is a simple technique that achieves spatial diversity in cooperative relay networks. However, for relay selection algorithms to make a selection decision, channel state information (CSI) from all cooperating relays is usually required at a central node. This requirement poses two important challenges.
