Abstract

Cooperative diversity is a novel technique proposed for conveying information
in wireless ad hoc networks, where closely located single-antenna network
nodes cooperatively transmit and/or receive by forming virtual antenna arrays.
For its building blocks, the relay channel and the two-transmitter, two-receiver
cooperative channel, we survey the latest advances made in determining the theoretical capacity bounds and describe the best practical code designs
reported so far. Both theory and practice predict that cooperative communication can provide increased capacity and power savings in ad hoc networks.
