Abstract

Due to the growing needs of positioning solutions serving for both emergency cases and daily life uses, many researches are carried out to enhance the existing techniques in a way to find a robust method that meets the expectations of both areas. In this paper, we propose an enhanced hybrid approach between the up-link time difference of arrival and Assisted GPS positioning methods for UMTS users by improving the accuracy of UTDOA using the NLMS adaptive filter instead of usual filter before performing the cross-correlation.
