Abstract
GNSS spoofing signals have the same signal structure as authentic signals, so it is difficult to mitigate the spoofing in time and frequency domains, and space domain processing has become one of the most powerful methods for spoofing cancelation. But most of the existing spoofing mitigation methods are implemented before signal despreading and their computational complexity is generally low, but their mitigation performance deteriorates seriously as the spoofing power decreases. To solve the problem, a spoofing mitigation method after signal despreading is proposed in this paper. Simulation results show that the proposed method is practicable and outperforms the methods before signal dispreading in a large variation range of spoofing power.
