Optimal signal and jamming dynamics embracing digital filter strictures

Abstract

Dynamic jamming/evasion duels are described purely in terms of re-design iterations for three separate agile FIR digital filters. At the signal generation end of the contest an optimal pulse-shaping filter works in concert with an optimal detection filter. At the jamming end, two strategies are evaluated for the re-design of the noise coloration filter. One of these utilizes an optimal square-rooting filter which (ideally) neutralizes the selectivity of the detection filter, while the other gives slightly less impressive jamming effectiveness but shows an exploitation advantage if it is known that the receiver recklessly uses a simple flip-template filter for detection.
