The present invention discloses a MIMO relay apparatus comprising a data source node, a relay node, and a destination node. The data source node sends a source send data x over a first radio channel H. The relay node receives a relay receive data y<SUB>r </SUB>from said first radio channel H, applying a relay transformation Phi to relay receive data y<SUB>r </SUB>to obtain a relay send data x<SUB>r</SUB>. The relay node further sends relay send data x<SUB>r </SUB>over a second radio channel G. The destination node receives a destination receive data y from second radio channel G, and applies a destination transformation Psi to destination receive data y to obtain a destination output data r representing an estimate of said source send data x. Relay transformation Phi and said destination transformation Psi are jointly tuned with respect to each other.
