1997 (English)In: Proceedings of Asilomar Conference on Signals, Systems & Computers, IEEE , 1997, 838-842 p.Conference paper (Refereed)
An algorithm for time delay estimation in an asynchronous direct-sequence code-division multiple access (DS-CDMA) system which exploits the structure of the system better than previously known algorithms, is presented. The different algorithms are compared through simulation and asymptotic analysis (large number ofvector samples). For a typical scenario it is shown that the proposed algorithm decreases the standard deviationof the time delay errors with a factor of approximately 2.
