Adaptive anti-jamming algorithm based on the spatial and temporal characteristics of GPS signal

In this paper, an algorithm is presented for adaptive anti-jamming in global position system (GPS). The proposed algorithm combines the subspace technique with the cyclic adaptive beamforming (CAB) algorithm so that it can suppress non-periodic jammers and/or those with different direction of arrival from the GPS signal simultaneously. Simulation results demonstrate the proposed algorithm can effectively suppress more complex jammers, even under very lower signal-to-noise ratio.
