Analysis of Jamming Effects on Noncoherent Digital Receivers

摘要

The effects of various jamming waveforms on conventional binary incoherent digital receivers was analyzed in terms of resulting receiver performance (i.e., receiver probability of error). Probability density functions associated with the test statistic generated by incoherent receivers under the influence of noise and jamming have obtained. Due to the complexity of the mathematical expressions specifying receiver probability of error in closed form, no attempt has been made to obtain absolute optimum jamming waveforms operating against binary incoherent receiver. Therefore, near optimum jammer signals were proposed, studied, and evaluated, The effect of a varying threshold on receiver performance was investigated and a jamming strategy involving use of an FM jammer was considered, and its effect evaluated. Graphical results are presented that highlight the mathematical results obtained.
