This thesis studies amplify-and-forward (AF) multiple-input multiple-output (MIMO) beamforming relay networks based on the minimum mean square error (MMSE) criterion under various transmit power restraints (TPRs). The primary contribution of this thesis is the derivation of a set of optimal relay amplifying matrices and source-destination beamforming vectors under diverse conditions of TPRs on the source and the relay for the AF MIMO wireless relay network. By comparing the bit error rate (BER) performance of each case, an efficient design of a half-duplex (HD) AF relay system is presented
