Abstract

Unexceptionally, modern global Navigation Satellite System (GNSS) adopt Direct Sequence Spread Spectrum (DSSS) signal structure, in which, correlation property of Pseudo Random Noise (PRN) code play an important role of affecting its rejection performance to Narrow Band Interference (NBI) and Multiple Address Interference (MAI). In order to mitigate the cross-correlation performance degradation due to tiered code construction, this paper proposes a new method for constructing complex sequence of GNSS civil signal. Based on any primary sequence of length L, Pseudo Random Initiate State (PRIS) transformation is used to construct a complex sequence of length NL, and a feasible generator scheme is presented. Simulation and analysis results shows, the acquisition complexity of PRIS sequence is similar to tiered code, and the correlation property of PRIS sequence is 4–5 dB better than tiered code, which approaches the performance of random sequence of length NL. The proposed method is applicable to civil GNSS signal designing, and is helpful to improve the receiving performance in challenge environment without distinct additional complexity, which will be attractive to GNSS users around the world.
