Research on the space-time anti-jamming algorithm for satellite navigation receiver

Nowadays, the satellite navigation system is widely used in various fields, such as military and civilian. While the satellite navigation signal is arriving at the ground receiver, the power is very weak and highly susceptible to interference. This will affect the performance of the receiver. Therefore, it is necessary to study the anti-jamming algorithm of the receiver. In this paper, a space-time interference suppression model is established, and then the LCMV-PI algorithm is analyzed and simulated. The simulation results show that, by using the LCMV-PI interference suppression algorithm, the deeper null can be formed in the direction of the interference signal and improved the output SINR of the system.
