Anti-jam space-time preprocessor for GPS based on multistage nested Wiener filter
Wilbur L. Myrick, M.D. Zoltowski, J. Scott Goldstein · 2003
An innovative space-time adaptive preprocessing algorithm based on a low complexity multistage nested Wiener filter is introduced. A closed form expression for the Wiener-Hopf filter weights is developed using the multistage nested Wiener filter parameters. It is demonstrated that this algorithm is capable of suppressing both wideband and narrowband jammers while maintaining low complexity.
