论文摘要
考虑了具有发射器波束成形和用户选择的Multiantenna Multiuser广播通道。与传统作品不同，我们考虑不完美的渠道状态信息（CSI），这是多用户广播渠道的实际情况。我们提出了在基站的强大正规化零强度（RRZF）。然后，我们表明，即使用户数量成长为无穷大，RRZF的表现优于零效（ZF）和正规化的ZF（RZF）光束。仿真结果验证了提出的鲁棒RZF波束形成的优势。
A multiantenna multiuser broadcast channel with transmitter beamforming and user selection is considered. Different from the conventional works, we consider imperfect channel state information (CSI) which is a practical scenario for multiuser broadcast channels. We propose a robust regularized zero-forcing (RRZF) beamforming at the base station. Then we show that the RRZF outperforms zero-forcing (ZF) and regularized ZF (RZF) beamforming even as the number of users grows to infinity. Simulation results validate the advantage of the proposed robust RZF beamforming.
