Abstract
A method and apparatus for receiving geolocation signals wherein the geolocation signals are received by receiving a plurality of perspectives of a geolocation signal and a jamming signal; generating a plurality of wavelet transformations corresponding to the plurality of perspectives; determining a covariance between corresponding elements in the plurality of wavelet transformations; weighting each element in each wavelet transformation by weights derived from the determined covariance; generating a nulled wavelet transformation by summing together corresponding weighted elements from each of the plurality of wavelet transformations; and generating a time-domain rendition of the geolocation signal according to the nulled wavelet transformation through use of the inverse wavelet transform.
