Abstract :
An algorithm for GPS receivers to calculate the optimal weights is proposed, which are orthogonal to all the steering vectors of jamming in the weight space. The optimal weights is obtained directly by the multiple signal classification (MUSIC) algorithm. It is suitable for both strong interference and weak ones. A comparison between this algorithm and the power-inversion algorithm has been done. The effectiveness of this algorithm is shown by the simulation results
