摘要：

In this paper a new H-infinity-type delay acquisition/tracking approach is proposed which is based on partitioning of the PN-code matrix of the CDMA users into submatrices which are then used to form a 'state-space' H-infinity-type linear combiner. The proposed novel formulation and approach is robust to modelling errors such as over- and underestimation of the number of signals present and provides a powerful near-far resistant delay-tracking solution in a multiuser DS-CDMA signal environment.
