Improving quality of time delay estimation in sound source localization using TDOA method
Keywords:
Sound Source Localization, TDOA, GCC-PHAT, GCC-PHAT- βAbstract
This paper presents several research results that enhance TDOA based sound localization accuracy with the priority of the source of interest. The GCC-PHAT algorithm is used to evaluate the estimated localization error. From that, we propose an adaptive method called GCC-PHAT-������ to improve time differences estimated, where the parameter ������ is adapted to the input parameters in TDOA method. From analisys and discussions are made on that design and using Monte Carlo simulations with the data collected in real environment, the results show the efficiency of our proposed method in TDOA based localization (compared to conventional TDOA based localization).
