Amplify-forward relaying for multiple-antenna multiple relay networks under individual power constraint at each relay Yasser Attar Izi 1 and Abolfazl Falahati1 department of Electrical Engineering Iran University of Science and Technology Tehran Iran Corresponding author Y Attar@ Email address YAI Y Attar@ AF afalahati@ Abstract This article considers the design of an optimal beamforming weight matrix of multipleantenna multiple-relay networks. It is assumed that each relay utilizes the amplify and forward strategy . it multiplies the received signal vector by
