摘要：

For multiple-input multiple-output (MIMO) relay systems, we present a Tucker-2 model based scheme for channel estimation. The channel training sequences at the source node are transmitted to the relay node for three-way space-time coding. Then the received signals at the destination node are formulated as a Tucker-2 model, and the source-relay and relay-destination channel matrixes can be estimated by alternating least squares (ALS) algorithm to fit this mode. At the same time, the feasibility of the proposed approach is analyzed in detail. The proposed scheme can preferably estimate the source-relay and relay-destination channel matrixes. Moreover, the estimation accuracies of source-relay and relay-destination channel are not interacted. Simulation results indicate the effectiveness of the proposed scheme.
