Array Processing and Unambiguous Positioning of Signals with Multi-Peak Correlations

J. A. García-Molina and J. A. Fernández-Rubio

Abstract: This paper discusses about unambiguous positioning with signals with multi-peak correlation functions when an array of antennas is featured by the GNSS receiver. In particular, the unambiguous positioning problem is treated as a multiple-input multiple-output (MIMO) estimation problem in which the available transmission and reception spatial diversities are jointly exploited. The simulation results show that an improved ambiguity resolution is achieved by exploiting all the available spatial diversities in the position domain, instead of tackling the ambiguity problem at single-satellite level. Therefore, the solution discussed is considered a promising approach for enabling the exploitation of the so-called high-order BOC signals and meta-signals in the presence of deep fading and strong multipath.
