Abstract

Millimeter wave (mmvave) bands offer enormous untapped spectrum for broadband radio communications. For high dimensional and sparse multiple input multiple output (MIMO) channels, analog beamforming (ABF) and digital multi-stream beamforming (DBF), collectively known as hybrid beamforming (HBF), enable low cost and low power-consumption radio architectures with near-optimal performance. It is easier and more efficient to learn such channels in beamspace than in spatial signal space. For radio frequency (RF) beam training, the Tx-Rx beam combination yielding maximum receiver output is selected. Noise can cause false beam selections manifesting in communication rate loss. In this paper, analytically derived closed-form expressions and simulation results for such noise performance evaluation have been presented.
