Two-Way Amplify-and-Forward MIMO Relay Communications Using Linear MMSE Receiver
In this paper, we derive the optimal structure of the source precoding matrices and the relay amplifying matrix for a two-way amplify-and-forward multiple-input multiple-output (MIMO) relay communication system where linear minimal mean-squared error (MMSE) receivers are used at both destinations.

| description | In this paper, we derive the optimal structure of the source precoding matrices and the relay amplifying matrix for a two-way amplify-and-forward multiple-input multiple-output (MIMO) relay communication system where linear minimal mean-squared error (MMSE) receivers are used at both destinations. We show that for a broad class of frequently used objective functions for MIMO communications, the optimal relay and source matrices have a general beamforming structure. Based on this optimal structure, a new iterative algorithm is developed to optimize the relay and source matrices. The performance of the proposed algorithm is demonstrated by numerical simulations. |
