Enhanced Beam Alignment for Millimeter Wave MIMO Systems: A Kolmogorov Model

27 Jul 2020 Qiyou Duan Taejoon Kim Hadi Ghauch

We present an enhancement to the problem of beam alignment in millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems, based on a modification of the machine learning-based criterion, called Kolmogorov model (KM), previously applied to the beam alignment problem. Unlike the previous KM, whose computational complexity is not scalable with the size of the problem, a new approach, centered on discrete monotonic optimization (DMO), is proposed, leading to significantly reduced complexity...
