Abstract :
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.
