... amplify-and- forward (AF), decode-and-forward [1], coded-cooperation [2], and compress-and-forward [3] have been presented. In [4], the outage and ergodic capacities have been analyzed for a three-node ... precoder and relay transceiver matrices in fast fading scenario can be impractical if the design is based on instantaneous channels [23]. Therefore, robust designs based on channel covariance information ... The common things among aforementioned works are that the transmitter, receiver, and the relays are all single-antenna nodes and the channel state information (CSI) (either instantaneous or second-order...
