In this paper, the sparse design of beamformers is studied. We employ the penalty decomposition method to constrain the l 0 -norm of the filters and investigate ...
Consider an N-element microphone array with L-tap FIR filter behind each of microphone in an acoustic environment, suppose the microphone elements have been set ...
Numerical results show that sparsity of the designed beamformers can be reduced without affecting very much of the performance.
Abstract. In designing acoustic broadband beamformers, the complexity can grow significantly when the number of microphones and the filter length increase.
Changing the spatial filtering function of a continuous ap- erture antenna is impractical. The purpose of this paper is to describe beamforming from a signal ...
