Abstract
In the previous chapters, we discussed options for data-dependent optimum beamforming for acoustic human/machine front-ends on cost-sensitive platforms of limited dimension. The main difficulties for realizing adaptive datadependent optimum beamforming were studied, which resulted in an attractive solution for practical audio signal acquisition systems using a robust generalized sidelobe canceller with spatio-temporal co nstraints. Various techniques for combining the RGSC with multi-channel acoustic echo cancellation as a complementary speech enhancement technique for full-duplex applications were analyzed.
