“…Compared with the CAB algorithm, the performance of the new algorithm improves while the computational load increases only a little due to the decomposition of the covariance matrix. In addition, as has been demonstrated in [5], the new algorithm outperforms the self-coherence algorithm in the terms of the convergence rate.…”

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.

“…arrival (DOA) information of the signals or both, employing traditional adaptive beamforming algorithms or some blind signal processing techniques [3,4,5,6,7,8,9,10,11,12]. Unlike the traditional beamforming methods, the power minimization method can form deep nulls in the interference directions without knowledge of the desired satellite signals and it also has a rather low computational complexity due to its simple structure [3,6].…”

Power minimization is a traditional method for interference suppression in satellite navigation systems. It works when the interferences are much stronger than the desired signals and noise, and its main advantage is that the direction of arrival (DOA) information of the desired signals is not required. In this paper, a new method for suppressing strong interferences for satellite navigation based on antenna arrays is proposed. The idea is to replace the auxiliary antenna outputs in the traditional power minimization method by the principal components of received array signals, leading to an improved performance, as verified by our simulations.

“…Researches on GPS interference suppression have been carried out more than one decade. Various kinds of adaptive processing algorithms have been proposed, including the power minimization approach [4], the adaptive beamforming [2,3] as well as blind adaptive beamforming algorithms [5][6][7]. The power minimization approach could form deep nulls in the beam pattern, with the nulls pointing to the direction of interference sources.…”

“…Adaptive beamforming could obtain higher signal-to-interference ratio (SIR) than the power minimization approach [2,3]. Blind adaptive beamforming suppresses interference by utilizing the characteristics of satellite signal such as cyclostationary [5][6][7].…”

In this paper, a novel adaptive interference suppression algorithm is proposed for high dynamic GPS (global positioning system) receiver. The new method incorporates derivative constraints on the interference DOA (direction of arrival) into power minimization approach, which could broaden the width of nulls in the interferences directions and adapt to the rapid change of the interference directions. Compared with the traditional wide nulling algorithm based on the derivative constraints, the new method does not have to know or estimate the DOAs of the desired signal and the interference. The new method is firstly discussed in the context of spatial processing, and then extended to space-time adaptive processing to mitigate wideband diffusive multipath interference. Effectiveness of the new method is verified via simulation examples.
