Performance analysis of an absolute phase modulation scheme for GNSS signals

We propose a digital modulation scheme, based on the generalization of the chirp signal, that allows to improve the performance of Global Navigation Satellite System receivers in scenarios affected by channel additive white Gaussian noise, narrowband interference and multipath. Different signaling schemes, characterized by autocorrelation functions with small secondary peaks, can be obtained by adjusting two parameters. The advantages of the proposed schemes regarding the sine BOC and CBOCpilot modulations are discussed.
