Abstract:	This paper considers blind adaptive antenna arrays as a possible solution to the interference cancellation problem in the GNSS context. The weight vector update in blind nullformers can introduce phase jumps not suitable for a generic GNSS receiver. In order to force a null imaginary part of the array’s response, we consider the design of two classes of blind symmetric arrays with conjugate symmetric weights. Finally, one of both provides a null phase response of the processor; the price is half the degrees of freedom of the array that cannot be used to cancel interferences.
