A Time-Domain Fingerprint for BOC(m, n) Signals
Binary offset carrier (BOC) describes a class of spread-spectrum modulations recently introduced for the next generation of global navigation satellite systems (GNSSs). The design strategies of these BOC signals have so far focused on the spectral properties of these signals. In this paper, we present a time-domain fingerprint for each BOC signal given by a unique histogram of counted time elap...
متن کاملMemory-efficient Time-domain Correlation for Boc-modulated Signals
In this paper, a signal acquisition algorithm for Galileo positioning is derived starting from the time domain correlation. The overall correlation is decomposed into coherent integration, smaller size correlations and combining with BOC removal. The complexity of this algorithm is compared in terms of memory consumption and arithmetic complexity. Estimates show a significant reduction in both ...
متن کاملReduced-complexity Time-domain Correlation for Acquisition and Tracking of Boc-modulated Signals
Recent proposals for the modernized GPS and Galileo receivers suggested the use of a new modulation type, namely the Binary-Offset-Carrier (BOC) modulation, in order to get a better spectral efficiency and reduced interference compared to the traditional BPSK modulation. The acquisition and tracking of the code phase delay and Doppler shift is typically based on the correlation between the rece...
متن کاملAcquisition Performance Analysis for BOC Modulated Signals
The advent of the new European satellite navigation system Galileo and the current study of a new generation of GPS satellites are increasing the interest towards navigation related systems, services and applications. Both the systems foresee improved performances with respect to the present GPS C/A code, mainly achieved by using novel modulation schemes for the signalsIn-Space. The Binary Offs...
متن کاملAn Unambiguous Tracking Scheme Using Partial-Pulses for BOC Signals
The recent researches on the tracking of binary offset carrier (BOC) modulated signals have been studied focusing on resolving the ambiguity problem caused by the multiple side-peaks in BOC autocorrelation. In this paper, we propose a novel unambiguous BOC tracking scheme with an improved tracking performance by using partial-pulses of BOC signals. Firstly, we observe that a sub-carrier consist...
