Abstract
According to the characters of GNSS receiver received interference signal is much stronger than the noise and the satellite signal. We apply subspace projection to space–time process. Improve the method of subspace projection based on the CCS-MSWF structure. It can estimate space–time two-dimensional subspace more quickly and exactly in the case of the limited data precision. Further obtain the optimal weight. This method is also suitable for small samples and signal changing scene. Compared with the original method. The accuracy of interference subspace estimate is improve without additional computational cost. Numerical simulation demonstrates that is effective and efficient to both narrowband and wideband interference. The performance of anti-jamming is excellent and stable.
