The usage of the millimeter wave (MMW) band in the 5th generation (5G) networks relies on beamforming to compensate the strong path-loss suffered at higher frequencies. In this work we propose a novel channel estimation method for MMW systems where both transmitter and receiver are equipped with less radio frequency chains than antennas and implement hybrid analog-digital beamforming.

Abstract

The usage of the millimeter wave (MMW) band in the 5th generation (5G) networks relies on beamforming to compensate the strong path-loss suffered at higher frequencies. In this work we propose a novel channel estimation method for MMW systems where both transmitter and receiver are equipped with less radio frequency chains than antennas and implement hybrid analog-digital beamforming.
