Efficient frequency-domain realization of robust generalized, sidelobe cancellers
Wolfgang Herbordt, Walter Kellermann · 2002
This paper deals with hands-free acoustical front-ends for human/machine interaction in competing talker situations using efficient frequency-domain implementations of a robust generalized sidelobe canceller (GSC). A new scheme is devised which leads to a factor of three of computational savings. The GSC tracking behavior is not impaired as the block lengths are kept sufficiently small.
