                                 ABSTRACT

Relay networks have received considerable attention recently, especially
when limited size and power resources impose constraints on the number of
antennas at each node. While fixed and mobile relays can co-operate to
improve reception at the desired destination, they also contribute to
unintended interference for neighboring cells reusing the same frequency.
In this work, we propose and analyze a relay scheme 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. If the intended destination lies at the periphery of the cell, then
the proposed scheme guarantees that the total power leaking into
neighboring cells is bounded. The optimal relay factors are provided for
both correlated and uncorrelated noise at the relays. Simulation results
are presented to verify the analysis.
