Abstract

This paper presents an interference cancellation and multipath mitigation algorithm for use in Global Positioning System (GPS) withan array antenna. It is shown that interference signals and multipath signals are effectively suppressed using a serial subspace projection method without any knowledge of the incoming directional information. After the subspace projections a beamformer is used to maximize the SNR of the received signal. The enhancement in the performanceis presented in terms of the cross correlation value and beam patterns.
