Abstract :
An architecture for the computation of time difference of arrival (TDOA) estimates is proposed. The structure of the various principal components is developed and a complexity analysis is presented. Realization using pipeline FFT and vector processing chips is considered. Conclusions are reached concerning the preferred spectral correlation and TDOA computing algorithms
