Abstract
The application of an adaptive all-pass based notch filter (ANFA) for the narrowband interference suppression in Global Positioning System (GPS) is proposed. The GPS that provides accurate positioning and timing information has become a commonly used navigation instrument for many applications. The adaptive notch filter is used to accurately estimate the narrowband jamming in real-time. It is based on all-pass filter with the Gaussian-Newton algorithm that can significantly improve the convergence rate by incorporating the so-called Hessian matrix. Simulation results show that the ANFA achieves a better performance than conventional linear predictors in terms of signal to noise ratio (SNR) improvement and mean square prediction error (MSPE) on the narrowband interference rejection in the GPS receiver.
