Abstract: This paper presents a novel unambiguous estimation technique of high-order BOC signals, dubbed the Double Optimization Multi-correlator-based Estimator (DOME). The DOME is a robust alternative to other unambiguous BOC estimation techniques found in the literature, being able to operate in harsh propagation conditions typical of urban environments, while fully exploiting the BOC signal properties. The approach followed consists of the solution of two parallel and dependent optimization problems in which N samples of the correlation function are exploited, solving the ambiguity problem at the same time that the high-order BOC accuracy is preserved. The preliminary performance assessment of the DOME in both controlled and realistic propagation conditions is presented, demonstrating the robustness and accuracy of the approach proposed.
