Abstract
We propose a digital modulation scheme, based on the generalization of the chirp signal, that allows to improve the performance of the Global Navigation Satellite Systems (GNSS) receivers in scenarios affected by channel additive whitre 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 CBOC modulations are discussed.
