Amplify-and-Forward Relay Networks Under Received Power Constraint With Imperfect CSI

The mobility of relay stations within a cell creates an interesting scenario where multiple sources, transmitting correlated data, can co-operate to satisfy power constraints at the receiving node. While beneficial to the receive node, this approach creates un-intended interference for neighboring cells reusing the same frequency. Previously, a relay scheme was proposed to simultaneously maximize SNR and minimize MSE, for an Amplify-and-Forward (AF) relay network operating under a receive power constraint guaranteeing that the received signal power is bounded to control interference to neighboring cells.
