Low-complexity robust adaptive wideband beamforming without tapped delay-lines or sensor delay-lines

What is it about?

This paper provides a novel beamformer without tapped delay-lines (TDLs) or sensor delay-lines (SDLs). It treats one wideband signal from a direction as multiple narrowband signals from an angular sector.

Why is it important?

Eliminating the TDLs and SDLs leads to a simpler system and lower computational complexity. Moreover, it outperforms traditional wideband beamforming methods in the case of limited snapshots or high signal-to-noise ratio (SNR).
