Beamspace Channel Estimation With Beam Squint Effect for the Millimeter-Wave MIMO-OFDM Systems
In this paper, we investigate two novel beamspace channel estimation schemes for millimeter-wave MIMO-OFDM systems relying on a uniform linear antenna array. Based on the sparse nature of the beamspace channel, compressive sensing-based methods can be adopted. Most of the existing wideband beamspace...
