Abstract

Relay selection is known to simplify signaling, avoid complex synchronization schemes, and also preserve the spatial diversity provided by the total number of relays available in the network. In this paper we investigate the effect of introducing relays of different types (relaying capabilities). We analyze opportunistic relay selection schemes in a heterogeneous multi-relay network with a single source, single destination with the existence of a direct link. The DMT for each network is calculated and it is shown that the new system enjoys the the benefits of the different relaying schemes at low and high multiplexing gains.
