Design of Robust Steerable Broadband Beamformers with Spiral Arrays and the Farrow Filter Structure

This paper extends the design of steerable broadband beamformers by incorporating robustness in the design formulation to cater for microphone mismatches and other non-ideal characteristics. In our method, a 2 norm constraint on the filter weights is imposed in the design optimisation problem. This...
