Partial band interference excision for GPS using frequency-domain exponents

Global Positioning System (GPS) receivers for military applications are highly sensitive to hostile jamming. This paper describes a partial band frequency-domain interference excision technique for GPS receivers. This has been demonstrated to be quite effective in field tests. Although the results of the field tests are classified [6] and not presented here, the algorithm is described in the paper along with a series of simulation results that demonstrate the effectiveness of this technique.
