In distributed millimeter-wave (mm-wave) multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) systems, the accurate and instantaneous beam direction is required to acquire high beamforming gain. Therefore, this study focuses on the tracking of angles-of-arrival (AoAs) and angles-of-departure (AoDs) in these systems. A mm-wave beam tracking method based on unscented particle filter (UPF) is proposed to track AoAs and AoDs of multiple paths in distributed mm-wave MIMO-OFDM systems. The proposed tracking method combines unscented Kalman filter (UKF) and particle filter (PF), which adds the observation value to update the particles through the UKF and can obtain higher tracking accuracy. Simulation results show that the proposed tracking method has better performance than the tracking method based on UKF under different observation noise variances and the antenna numbers equipped at the transmitter and the receiver.
