Analysis of anti-interference performance of navigation signal based on FH-BOC modulation system

Based on the existing BOC modulation system, we propose a new navigation signal system based on Frequency Hopping-BOC (FH-BOC) is proposed. This paper establishes the mathematical model of FH-BOC, and analyzes some representative FH-BOC signal characteristics. The results show that the proposed FH-BOC signal has excellent code tracking performance, anti-interference and anti-multipath performance. The proposed modulation scheme can provide a new idea for the design of the next generation GNSS navigation signal system.
