Abstract

This contribution relates the robust generalized sidelobe canceller (RGSC) with an adaptive blocking matrix (ABM) after Hoshuyama et al. for non-stationary broadband signals with linearly constrained minimum variance (LCMV) beamformers. While alternative approaches only exploit spatial wave field characteristics, it is shown that the ABM introduces dependency on the desired signal power spectral density (PSD) into the array look-direction constraints. The ABM yields better interference suppression than for stationary frequency independent look-direction constraints, since the ABM does not suppress frequencies without desired signal components.
