Design and Performance Analysis of A Communication and Navigation Fusion Signal

Abstract

Intended to achieve a signal design with high spectrum utilization efficiency and high measurement accuracy within a limited bandwidth, in this paper, a modulation scheme of communication and navigation fusion signal is presented by combining continuous phase modulation and spectral overlay. The results show that the proposed signals perform well on the anti-multipath performance and ranging accuracy while theoretically possess good compatibility to other navigation service signals in S-band. This modulation scheme can generate flexible waveforms that provide reference to design fusion communication and navigation signals. It has a positive impact on the construction of location based services equipped with higher ranging accuracy and higher tracking sensitivity.
