摘要：
Improvements in denoising, in conjunction with wavelet processing, are proposed for estimating the time difference of arrival (TDOA) of signals received at two spatially separated sensors. Wavelet denoising, based on a modified maximum likelihood method and higher order moments, are proposed to improve the performance. A numerical evaluation of the methods, when unequal SNR conditions prevail is presented.
