Adaptive min-max filtering in spread-spectrum channels with very fast frequency-hop disturbances
Daniel Graupe, JOHN UTH · International Journal of Systems Science · 1987
A min-max filtering technique is presented which uses a semi-adaptive policy to filter out a narrowband jammer in a spread-spectrum channel. This technique is compared with adaptive whitening and is shown to be superior because of its reduced computational requirements and its improved signal-to-noise ratio for cases of very fast frequency-hop jamming where there is insufficient time for adequate signal identification as required for least-squares whitening filters.
