Difference of arrival estimation using wavelet transforms
Ralph D. Hippenstiel, Unal Aktas · 2003
Accurate localization of a mobile wireless communication unit via a Time Difference of Arrival (TDOA) method is addressed. Wavelet denoising is used to enhance the TDOA estimation. A 79 to 81 percent improvement relative to raw data processing is obtained using a modified approximate maximum likelihood method or its time varying enhancement, respectively.
