Composite meander noise-like signals (CBOC signals) of perspective satellite radio navigation systems


M.S. Yarlykov – Dr.Sci. (Eng.), Professor

Composite meander noise-like signals, referred to composite binary offset carrier modulated signals (CBOC signals), are of substantial interest for application in new generation satellite radio navigation systems (SRNSs), in particular, the European Galileo system and, as it is supposed, at the third development stage of the Chinese BeiDou/Compass system. The CBOC spreading modulation for modernized Galileo E1 signals are analyzed. The formation and structure of CBOC signals are considered. The block diagram of the CBOC signals satellite transmitter where is realized CASM algorithm is obtained. The envelope and phase of entire CBOC signals are analyzed. CASM algorithm is used to ensure that the signal transmitted from the satellite has a constant power envelope. Analytical expressions for power spectral densities of single elements of modulating functions of entire CBOC–signals are obtained. Plots are depicted, and the properties of power spectral densities are discussed. The tracking performances (especially in multipath scenarios) of these CBOC signals are significantly improved compared to pure BOC(1,1) signals tracking. A CBOC signals provides additional benefits over BOC(1,1) signals including better radiofrequency compatibility with C/A code signals that also is transmitted at 1575,42 MHz. Practical characteristics are analyzed on the basis of the CBOC(6,1,1/11) modulation, which is typical of the Galileo and the BeiDou–2/Compass SRNSs.
