Tensor-Based Joint Channel and Symbol Estimation for Two-Way MIMO Relaying Systems

In this letter, we present two closed-form semiblind receivers for a two-way amplify-and-forward relaying system. The proposed receivers jointly estimate the symbol and channel matrices involved in the two-way relaying system by exploiting tensor structures of the received signals at the relay and t...
