Abstract: A novel beamformer without tapped delay lines (TDLs) or sensor delay lines (SDLs) is proposed. It treats one wideband signal from a direction as multiple narrowband signals from an angular sector. To preserve the signal… read more here.

DOI: 10.1109/jsac.2021.3071822
Abstract: The combination of large bandwidth at terahertz (THz) and the large number of antennas in massive MIMO results in the non-negligible spatial wideband effect in time domain or the corresponding beam squint issue in frequency… read more here.
