A New GPS Adaptive Anti-jamming Algorithm in Multi-interference Circumstance

In order to find a method to eliminate the GPS receiverpsilas interference, the paper studied the principle of two conventional adaptive algorithms: Sample Matrix Inversion (SMI) adaptive algorithm and Gram-Schimit (GS) algorithm based on adaptive digital wave beam producing process. This paper analyzed a new algorithm: Improved Gram-Schmit (IGS) algorithm. Also, simulations of three algorithms are carried out and anti-jamming performance of them is compared. Conclusion is that IGS algorithm is a balanced fine algorithm because of its low computation cost, stable interference suppression performance, and easy engineering implementation process.
