Abstract
In this paper, we present a modification on delay estimation and tracking using the unscented filter for an asynchronous CDMA system. The algorithm is based on utilizing the minimum excess mean square error criteria (MEMSEC) in deriving the filter update equation. Computer simulations are presented to illustrate the new filter's performance. More specifically, the delay estimation errors for multipath multiuser CDMA systems are evaluated using the unscented and the proposed modified unscented filters. The results show that the modified unscented filter tracks the delay variations with less errors than the unscented filter.
