Abstract
Antenna arrays with adaptive algorithms are widely used to provide anti-jamming abilities for Global Navigation Satellite System (GNSS) receivers, among which Power-Inversion (PI) algorithm is attractive for suppression of jammers before de-spreading of signals and simplicity for implementation. Most of previous works either selected the reference element arbitrarily or naturally selected the center element of the array geometry as reference. In this paper, we studied the effect of reference element selection on the performance of the adaptive array receivers. The results show that although the selection of reference element has negligible effects on interference cancellation, it does affect the array gain in the direction of desired signal as well as the array output signal-to-interference-plus-noise ratio (SINR). When the optimal reference element is selected, it will give more than 30% improvement in terms of available angular region under no SNR loss condition over arbitrary reference element selection.
