Performance Evaluation of the Turbo DLL Architecture.

The design of for Galileo receivers is driving the research towards novel architectures with improved capabilities. In this paper the specific aspect of robustness to the presence of multipath is addressed, introducing a novel architecture for code tracking loops. Such a scheme aims at tracking in a separate way the multipath components in order to cancel them from the input signal. The architecture has been named “Turbo Delay Lock Loop” being based on an iterative procedure boosting the tracking performance after a transient time. The paper theoretically describes the architecture and presents simulation results demonstrating the improvedcapabilities with respect to common DLL-based code loops. The Turbo DLL architecture has been patented by the authors
