Heterogeneous networks are a promising technology in fifth generation (5G) wireless networks, which has been shown to significantly increase the capacity and coverage compared with the conventional wireless networks. In this paper, we consider the robust multiple-input single-output beamforming design in a two-tier heterogeneous network. By considering the worst case deterministic model, our objective...
In this paper, we develop the robust transceiver optimization for the multiple-input single-output (MISO) interference channels where each transmitter (Tx) is equipped with multiple antennas and each single-antenna receiver performs simultaneous wireless information and power transfer (SWIPT) based on a power-splitting architecture. Assuming imperfect channel state information (CSI) at the Txs, we...
