摘要:

这封信研究了深度学习(DL)方法,以优化下行链路多用户多天线系统中的波束成形向量,这些方法可以普遍应用于基站处的任意给定发射功率限制。我们利用总功率预算作为边信息,以便深度神经网络(DNN)可以有效地学习波束成形优化中功率约束的影响。因此,单个训练过程对于所提出的通用DL方法是足够的,而常规方法需要针对所有可能的功率预算水平训练多个DNN。数值结果表明,所提出的DL方法比现有的计划的有效性。

英文摘要:

This letter studies deep learning (DL) approaches to optimize beamforming vectors in downlink multi-user multi-antenna systems that can be universally applied to arbitrarily given transmit power limitation at a base station. We exploit the sum power budget as side information so that deep neural networks (DNNs) can effectively learn the impact of the power constraint in the beamforming optimization. Consequently, a single training process is sufficient for the proposed universal DL approach, whereas conventional methods need to train multiple DNNs for all possible power budget levels. Numerical results demonstrate the effectiveness of the proposed DL methods over existing schemes.
