Abstract
In this paper, hybrid beamforming design for multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems is studied over the indoor millimeter wave (mmWave) channels. Under practical hybrid beamforming constraints for multicarrier systems, we propose the sub-system SVD hybrid beamforming design which provides good performance with low complexity. Moreover, we reduce the amount of the required channel state information (CSI) in our design based on the statistical properties of indoor mmWave channels. Simulation results show that our design achieves the performance of traditional full-digital beamforming even if the amount of CSI is greatly reduced.
