摘要

我们提出了一种基于啁啾信号泛化的数字调制方案，该方案可以提高全球导航卫星系统接收机在信道加性高斯白噪声、窄带干扰和多径影响下的性能。通过调整两个参数，可以得到具有小二次峰的自相关函数的不同信号方案。讨论了正弦BOC和cboc导频调制方案的优点。

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.
