Enhanced CADLL Structure for Multipath Mitigation in Urban Scenarios

X. Chen, F. Dovis

Abstract:	The Coupled Amplitude Delay Lock Loops (CADLL) was recently proposed proving very good performance in multipath mitigation if compared to other techniques such as high resolution correlator (HRC). In this paper an improvement of the basic CADLL architecture is introduced. New features are embedded and the working procedure is refined to make the CADLL able to mitigate multipath carrier phase error as well and mitigate multipath error in severe environment by using multiple Units. Thus, the new architecture is named Enhanced CADLL. Both the multipath code phase error envelopes and the multipath carrier phase error envelopes for different scenarios are presented in this paper to demonstrate the performance of the ECADLL structure.
