Beam Tracking Under Highly Nonlinear Mobile Millimeter-Wave Channel

초록

We propose approaches to the problem of multi-paths beam tracking in millimeter-wave (mmWave) mobile communications. Precise angle tracking is necessary to take advantage of beamforming technology in this mmWave band. The mobile channel is a highly nonlinear function with respect to the state that comprises the beam angle and the channel path gain. Therefore, the beam angle tracking is challenging and crucial. We propose a couple of particle filtering frameworks for beam tracking and show outperforming result of an auxiliary particle filtering approach over recently proposed tracking approaches.
