Abstract
This correspondence on the use of crosspower-spectrum phase (CSP) analysis as an accurate time delay estimation (TDE) technique. It is used in a microphone array system for the location of acoustic events in noisy and reverberant environments. A corresponding Coherence Measure (CM) and its graphical representation are introduced to show TDE accuracy. Using a two microphone pair array, real experiments show less than 10 cm average location error in a 6m x 6m areaFile in questo prodotto:
