We propose an efficient method for the detection of Line of Sight LOS and Multipath MP signals in global navigation satellite systems GNSSs which is based on the use of virtual MP mitigation VMM technique. By using the proposed method, the MP signals’ delay and coefficient amplitudes can be efficiently estimated. According to the computer simulation(More)
The Multiplexed Binary Offset Carrier (MBOC) signal has been recommended as optimized modulation on L1/El frequency band by both United States and European Union communities. MBOC signal is defined on the basis of its spectrum, while different time waveforms can be selected as possible modulation candidates. In this paper we present the different options of(More)
In this paper we propose the derivation of the expressions for the non-coherent Delay Locked Loop (DLL) Discriminator Curve (DC) in the absence and presence of Multipath (MP). Also derived, are the expressions of MP tracking errors in non-coherent configuration. The proposed models are valid for all Binary Offset Carrier (BOC) modulated signals in Global(More)
In this paper, we propose an efficient scheme for side peak cancelation in binary offset carrier (m,n) (BOC(m,n)) with integer modulation order. The proposed scheme reduces significantly the width of the main peak of the auto-correlation function (ACF) and thus the range of influence of the multipath (MP) in BOC-modulated signals. It is based on the use of(More)
In this paper, an efficient scheme for Multipath mitigation in Global Navigation Satellite System (GNSS), such as Global Positioning System (GPS) and future Galileo, is proposed. It is based on Centered-Finite-Derivatives by using Five-Point-Stencil. By using the aforementioned scheme, the multipath induced bias can be efficiently reduced. In addition,(More)
Global navigation satellite system “GNSS” is defined as a set of positioning satellite systems offering the possibility for a receiver to determine its position at any time and in any place on earth. The accuracy of this calculation, which is extremely solicited, is disputed by the phenomenon of multipath. for this purpose, several multipath(More)
