Abstract
We study the problem of determining the optimum
power allocation policy for an average power constrained jammer operating over an arbitrary additive noise channel, where the aim
is to minimize the detection probability of an instantaneously
and fully adaptive receiver employing the Neyman-Pearson (NP) criterion. We show that the optimum jamming performance can be achieved via power randomization between at most two different power levels. We also provide sufficient conditions for the improvability and nonimprovability of the jamming performance via power randomization in comparison to a fixed power jamming scheme. Numerical examples are presented to illustrate theoretical results.
