Sound Source Localization

Classical algorithms of sound source localization with beamforming and high-resolution spectral estimation.

Usage

matlab -nodesktop -nosplash –r matlabfile (name of .m)

Algorithm Interpretation

  • Beamforming: a spatial filtering method, is a signal processing technique used in sensor arrays for directional signal transmission or reception.
  • MUSIC: Multiple Signal Classification
  • ESPRIT: Estimation of Signal Parameters via Rotational Invariance Technique
  • MVDR: Minimum Variance Distortionless Response
