摘要：
This paper deals with the synthesis and the performance analysis of multiuser delay estimators of multipath channels according to the Maximum Likelihood (ML) criterion in Data Aided (DA) mode for a BPSK DS-CDMA uplink. We suppose the channel tap weights ate known perfectly, and we are interested in the estimation of the path delays. We perform open-loop (S-curve) and closed loop Mean Squared Estimated Error (MSEE) analysis in tracking mode and we compare the results to the classical Cramer-Rao Lower Bound (CRLB).
