Spectral shaping of Galileo signals in the presence of frequency offsets and multipath channels

چکیده
Recently, the authors have proposed a new class of BinaryOffset-Carrier (BOC) modulation, namely the Double-BOC (DBOC) modulation which generalizes the main modulation types used in GPS and Galileo under a single, unified formula, and allows extra-flexibility in designing the suitable spectral shaping of future GNSS signals. The goal of this paper is to extend the previous analysis to multipath channels and to study the interference between various DBOC-modulated signals and the standard GPS signals in the presence of frequency offsets.

Correlation properties of Multiplexed Binary Offset Carrier (MBOC) modulation
Recently, a Multiplexed Binary Offset Carrier (MBOC) modulation has been recommended by the GPS-Galileo Working Group on Interoperability and Compatibility in order to increase the tracking abilities of Galileo Open Service signals and of GPS L1 civil signal. MBOC modulation also ensures a better spectral separation with C/A codes. The purpose of this paper is to analyze the MBOC properties in ...
متن کاملEnergy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels
In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...
متن کاملSingle-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...
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...
متن کاملA Tree-Structured Blind Algorithm for Joint Parametric Channel Estimation and Non-coherent Data Detection in an OFDM-CDMA Wireless System with Antenna Arrays
A blind joint parametric channel estimation and noncoherent data detection algorithm is proposed for the downlink of an orthogonal-frequency-division-multiplexing code-division-multiple-access (OFDM-CDMA) system with multiple-input-multiple-output (MIMO) antenna arrays. To reduce the computational complexity, we first develop a tree-structured algorithm to estimate high dimensional parameters p...
