Anti-Jamming Communication Using Slotted Cross Q Learning

open access: yesElectronics, 2023
Most of the existing intelligent anti-jamming communication algorithms model sensing, learning, and transmission as a serial process, and ideally assume that the duration of sensing and learning timeslots is very short, almost negligible. However, when the jamming environment changes rapidly, the sensing and learning time can no longer be ignored, and ...

Optimal Jammer Placement in Wireless Localization Systems [PDF]

open access: yes, 2016
In this study, the optimal jammer placement problem is proposed and analyzed for wireless localization systems. In particular, the optimal location of a jammer node is obtained by maximizing the minimum of the Cramer-Rao lower bounds (CRLBs) for a number

Fast Reinforcement Learning for Anti-jamming Communications

open access: yes, 2020
This letter presents a fast reinforcement learning algorithm for anti-jamming communications which chooses previous action with probability $ $ and applies $ $-greedy with probability $(1- )$. A dynamic threshold based on the average value of previous several actions is designed and probability $ $ is formulated as a Gaussian-like function to guide

Anti-jamming performance of chaotic digital communication systems [PDF]

open access: yesIEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2002
Among the various modulation schemes proposed for chaos-based digital communications, chaos-shift keying (CSK) and differential chaos-shift keying (DCSK) have been most thoroughly analyzed and considered for practical implementation. One important aspect of performance of any communication system is the ability to resist jamming.
