Abstract:
A method for minimizing an effect of at least one interference signal while minimizing the distortion of at least one GPS satellite signal, the method comprising the steps of:receiving the at least one interference signal and the at least one GPS satellite signal by a plurality of antenna elements and processing the received signals; and filtering the received processed signals by a plurality of multiple tapped delay line structures based a plurality of filter coefficients, whereby the plurality of filter coefficients equals R{tilde over (xx)}âˆ’1C[CHR{tilde over (xx)}âˆ’1C]âˆ’1F wherein CH{tilde over (w)}=F, where {tilde over (w)} equals the plurality of filter coefficients, R{tilde over (xx)} equals a covariance matrix, and C and F are determined to preserve a frequency spectrum of the at least one GPS satellite signal.
