Novel multiplexing technique in anti-jamming GNSS receiver

This paper proposes the multiplexing technique that combines signal detector, decision logic, and anti-J modules to counteract narrowband continuous wave interference and spoofing signal in global navigation satellite system (GNSS) receivers. The signal detector is to detect the presence of different types of jammers. The decision logic is utilized to select different anti-jam strategies against jammers. Effective carrier to noise ratio (C/No) is employed to assess the performance of proposed scheme. Through the establishment of mathematical model and simulation results, the proposed scheme can effectively detect and mitigate jammers so that the positioning performance of GNSS receivers will not be contaminated.
