the Cramer-Rao low bound (CRLB) for mobile station location based on time of arrival (TOA) in CDMA system is obtained.The detailed deduction and the expression of CRLB are showed and the physical interpretation is discussed.From the CRLB
the conclusion that the CRLB for location is not related with user's numbers is obtained.A new time delay estimation algorithm which can restrain muti-user interferes (MUI) is raised.The method explains the CRLB more sufficiently.The paper discusses some numerical examples based on simulation experiments.
