ABSTRACT:
Recently, multiple-input
multiple-output (MIMO) relay technique has been received great attention due to
its prominent ability to provide broad coverage and enhance the link
reliability and spectral efficiency. In this paper, an overview of optimal
design for single user and multiuser non-regenerative MIMO relay systems is
proposed. We explore some key designs of source node and destination node as
well as relay node processing matrices using minimum mean square error (MMSE)
criterion under the transmit power constraints. Simulation results compare
different methods in terms of the MSE and bit error rate (BER) performance.
