Spectral analysis and waveform optimization of signals for future GNSS

Abstract:

Based on in-depth analysis of the modulated signal spectrum, the waveform optimization of the continuous phase carrier modulation is developed including two methods of approximate reconstruction and analytic construction in order to get more compact power distribution without useful information loss. The modulated waveforms having very high spectral efficiency by both of the methods are more conducive to the signal acquisition and tracking using the phase-locked loop structure for future GNSS.
