Steering Study of Linear Differential Microphone Arrays
Differential microphone arrays (DMAs) can achieve high directivity and frequency-invariant spatial response with small apertures; they also have a great potential to be used in a wide spectrum of applications for high-fidelity sound acquisition. Although ...
A robust minimum variance beamformer with new constraint on uncertainty of steering vector
Signal processing in UWB communicationsA robust minimum variance beamformer, also called robust Capon beamformer (RCB), with a new constraint on the uncertainty of nominal array steering vector (ASV) is proposed in this paper. Unlike the uncertainty constraints used in literature, the ...
Adaptive beamformer derived from a constrained null steering design
In the environment where the desired signal is stronger or not significantly weaker than the interferences, nulling in the direction of interest becomes a problem for conventional zero tracking algorithm. The null steering algorithms with single and ...
