摘要: In this paper, we develop a beamforming algorithm for multiuser MIMO-relaying wireless systems. We consider relaying scenario with multiple sources transmitting to one or more destination nodes through several relay terminals. Each is equipped antennas. jointly design the matrices of cooperating relays by minimizing both noise received at each node and interference caused not targeting node. impose additional constraints that preserve signal from source its targeted The problem shown be convex optimization formulated as second-order cone program can efficiently solved using interior point methods. Numerical simulations are presented showing superior performance our technique compared previously proposed zero forcing beamforming.
