A Side-Peak Cancellation Scheme for CBOC Code Acquisition
نویسندگان
چکیده
In this paper, we propose a side-peak cancellation scheme for code acquisition of composite binary offset carrier (CBOC) signals. We first model the family of CBOC signals in a generic form, and then, propose a side-peak cancellation scheme by combining correlation functions between the divided sub-carrier and received signals. From numerical results, it is shown that the proposed scheme removes the side-peak completely, and moreover, the resulting correlation function demonstrates the better power ratio performance than the CBOC autocorrelation. Keywords—CBOC, side-peak, ambiguity problem, synchronization

An Improved Unambiguous CBOC Signal Tracking Scheme in the Galileo System
Based on the cancellation and reinforcement of the autocorrelation side-peaks and main-peak, respectively, this paper proposes an improved unambiguous tracking scheme for composite binary offset carrier (CBOC) signals used in the Galileo system. Dividing the CBOC autocorrelation into multiple partial correlations, first, we obtain individual correlation components making up the autocorrelation ...
متن کاملUnambiguous Acquisition for Galileo E1 OS Signal Based on Delay and Multiply
Abstract Galileo E1 Open Service (OS) signal is transmitted with the modulation of Composite Binary Offset Carrier (CBOC). CBOC has a main drawback that is the autocorrelation function has multiple sidepeaks, which will lead to ambiguous acquisition. The high rate of data bit and secondary code makes it very difficult to increase coherent integration time. This paper will propose a new scheme b...
متن کاملA Novel Correlation Function for CBOC Signal Synchronization
Binary offset carrier (BOC) signal synchronization is based on the correlation between the received and locally generated BOC signals. Thus, the multiple side-peaks in BOC autocorrelation are one of the main error sources in synchronizing BOC signals. Recently, new correlation functions with no side-peak were proposed for sine and cosine phased BOC signal synchronization, respectively, by the a...

The aim of this paper is to analyze the impact of spreading codes cross-correlation on code tracking performance, and to optimize the data-pilot code pairs of Galileo E1 Open Service (OS) Composite Binary Offset Carrier (CBOC) signals. The distortion of the discriminator function (i.e., S-curve), due to data and pilot spreading codes cross-correlation properties, is evaluated when only the data...
متن کاملSidelobes Cancellation Method for Unambiguous Tracking of Binary-offset-carrier Modulated Signals
The signals proposed for the future European Galileo system and the GPS M-code signals use split-spectrum-type modulations, such as Binary-Offset-Carrier (BOC) modulation. Sine and cosine BOC modulations multiply the spreading code with rectangular sub-carriers and create a split-spectrum signal with the main lobes shifted around the sub-carrier frequency. This type of modulation brings multipl...
