  六、内容简介:

  The joint design of hybrid beamforming matrices is conceived for multiuser mmWave full-duplex (FD) multiple-input multiple-output (MIMO) relay aided systems in the presence of realistic channel state information (CSI) errors. Specifically, we maximize the system’s worst-case sum rate by jointly optimizing the base station’s (BS) analog and digital beamforming matrices, plus the analog receive and transmit beamforming matrices of the relay station (RS) as well as the digital amplify-and-forward (AF) beamforming matrix of the RS under practical constraints. Explicitly, the transmit power constraints of the BS and RS, the residual self interference power constraint of the RS, the per-user quality of service constraints and the unit-modulus constraints imposed on the analog beamforming matrix elements are all taken into account. Since the resultant optimization problem is very challenging due to its highly nonlinear objective function and nonconvex coupling constraints, we first transform it into a more tractable form. We then develop a novel joint optimization algorithm based on the penalty dual decomposition (PDD) technique to solve the resultant problem. The proposed algorithm converges to the set of stationary solutions of the original optimization problem. We show that our FD hybrid mmWave MIMO relay system significantly outperforms both its nonrobust counterpart as well as the conventional half-duplex counterpart.
