Time difference of arrival estimation of unequal SNR denoised communication signals
S. Mantis, Ralph D. Hippenstiel · 2002
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 the 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.
