Abstract:

A refinement of the results obtained for optimum energy constrained jamming of digital receivers is obtained by modeling the jammer as a random process. In the modeling process, a random time arrival or random frequency errors are accounted for by including these effects in the representation of the jamming waveforms. Performance analyses are carried out in order to determine the effect of random time of arrival and random frequency errors on the part of the jammer, on the receiver probability of error. The mathematical results derived are programmed, evaluated on the computer, and compared against ideal optimum energy constrained jamming strategies previously studied. Results for both coherent and incoherent receivers are derived and analyzed utilizing conventional binary modulation schemes. Results show that generally some but not a great deal of jammer effectiveness is lost due to random time arrival or random frequency errors associated with the jammer waveform.
