What is a "Jammer Optimization"? The Most Authoritative Explanation.

Can a jammer find the optimal jamming strategy in a limited time?

As high complexity will lead to a long convergence time, the jammer can hardly find the optimal jamming strategy in a limited time, which can be fatal to the protected target. To overcome the problems above, a two-level jamming decision-making framework is developed in this paper.

How a smart jammer system can be viewed as a reaction?

The designed jamming waveform results are sent back to the system controller to form the next jamming scheme. Therefore, the smart jammer system can be viewed as a reaction to the electromagnetic environment, based on which it optimally designs the jamming waveforms. To sum up, the major contributions of this work are summarized in the below: 1.)

How to minimize the total jamming power?

Specifically, with the derived expressions of SINR and MI, two associated LPI-based jamming waveform design criteria are proposed, which minimize the total jamming power by optimizing the transmitted jamming waveform while the achieved SINR/MI is enforced to be below a certain threshold. 3.)

What is cooperative jamming based on collaboration?

Recently, cooperative jamming based on collaboration has been seen as an effective solution for secure communications and has been investigated in many papers in the literature (e.g., cooperative jammer , , energy harvesting jammer , ).
