Several diversity techniques have been proposed to cope with fading in wireless networks. A recent and promising technique, which does not increase hardware demands, is cooperative communication. Here spatial diversity is created by using other terminals to relay the information from the source terminal to the destination terminal. Cooperative protocols proposed in literature are often studied under...
In this paper, we present a new low-complexity relay selection scheme for channel-state information (CSI)-assisted dual-hop amplify-and-forward (AF) cooperative networks. The scheme is mainly based on the switch-and-examine (SEC) diversity combining technique where a relay out of multiple relays is only used to forward the source signal to destination. The selection process is performed based on a...
