A novel method is devised to jointly estimate the channel matrices involved in a relay-assisted MIMO communication system. We first propose a trilinear coding structure to be used at the amplify-and-forward (AF) relays for combining the received signals while spreading the combined signals across transmit antennas and time blocks, before retransmission.(More)
We propose a novel joint channel estimator for a relaying MIMO communication system. Considering a three-hop relaying protocol, our combined alternating least squares (Comb-ALS) algorithm obtains cooperative diversity by fully exploiting the tensor algebraic structures of the available cooperative MIMO links. This is achieved by coupling the tensor data for(More)
