Abstract

Abstract: Aiming at analysis requirement to anti-multipath performance of satellite navigation signal system, on the basis of expounding modulation types of latest navigation signal system on L1/E1/B1(1575.42MHz) frequency band, the analytical expressions of code tracking multipath error envelope and carrier phase multipath error based non-coherent early minus late process discriminator and arctangent discriminator was deduced respectively, the effect of receiver correlation distance, receiver front-end bandwidth and navigation signal modulation types to multipath error were analyzed through simulation. The results show that B1-C open service signal of BDS should adopt MBOC(6,1,1/11) modulation of similarly Galileo E1OS combination mode, and B1 authorized signal of BDS recommend to optimize for BOC_cos (15,2.5) modulation in order to improve anti-multipath performance.
