A NULLER WITH NO SATELLITE SIGNAL DISTORTION

摘要

Interference in a GPS receiver in minimized while preserving the GPS satelli te signal in a system having N antenna elements for receiving the interference signal and the satellite signal and multiple tapped delay line structures connected to the antenna elements (160) for filtering the signals received b y the antenna elements based a plurality of filter coefficients. The filter coefficients are determined such that the plurality of filter coefficients equals Rxx-1C~CHRXX-1C~-1F wherein CHW = F, where w equals the plurality of filter coefficients, Rxx equals a covariance matrix, and C and F are determined to preserve a frequency spectrum of the GPS satellite signal.
