sensor array and multichannel signal processing workshop
作者: A. Leshem N. Petrochilos A.-J. van der Veen Department ITS/Electrical Engineering Delft University of Technnology Delft Netherlands
We prove that mixtures of continuous constant modulus sources can be identified with probability 1 with a finite number of samples (under noise-free conditions). This strengthens earlier results which only considered ... 详细信息

sensor array and multichannel signal processing workshop
作者: P.G. Georgiou C. Kyriakakis Immersive Audio Laboratory-Integrated Media Systems Center University of Southern California Los Angeles CA USA
We investigate an alternative model for signals encountered in acoustic environments to the traditional Gaussian process. The sound signals in this case are assumed to be sub-Gaussian of impulsive nature. The noise en... 详细信息

sensor array and multichannel signal processing workshop
作者: D.J. Rabideau Lincoln Laboratory MIT Lexington MA USA
Adaptive beamforming based on sample matrix inversion requires the availability of a secondary data set for "training" (i.e., estimating the sample covariance matrix). For each snapshot processed, near-optim... 详细信息

sensor array and multichannel signal processing workshop
作者: S. Kraut J.L. Krolik Department of ECE Duke University Durham NC USA
We present an approach for suppressing moving interference in shallow water environments. Adaptive beamforming techniques are based upon applying a covariance matrix inverse or projection operator to the data, in orde... 详细信息
