This letter introduces the concept of antifragile electronic warfare (EW), which we define as the ability to allow a communications link to improve performance due to the presence of a jammer. This concept should not be confused with jamming countermeasures (a.k.a. anti-jamming or electronic protection). Rather, antifragile EW can be thought of as the next step beyond simply avoiding or mitigat...

Two delay estimators that mitigate effects of a tone jammer are presented. They are based on the phase interference extractor (PIE) and auxiliary-vector (AV) data detection principles. The estimators are analyzed by computer simulations and shown to tolerate more powerful jammers than the conventional correlator estimator does.

The E-911 mandate from the Federal Communications Commission (FCC) requires a mobile 911 caller location to be established for 67 percent of calls to within 50 meters, and 95 percent of calls to within 150 meters for wireless handset-based solutions. To meet the E-911 requirement, a GPS receiver can be incorporated into mobile phones which use frequency modulated (FM) signals for communications...

Method for applying spread-spectrum techniques to optical communication is presented. The interference suppression capability of spread-spectrum systems is shown to be enhanced by optical transform domain processing.Effects of jammer in DSSS communication system are demonstrated in thispaper.Several possible implementations of this system are suggested, and applications to fiber optics, laser r...

In this paper, we propose a two-way secure communication scheme where two transceivers exchange confidential messages via a wireless powered untrusted amplify-and-forward (AF) relay in the presence of an external jammer. We take into account both friendly jamming (FJ) and Gaussian noise jamming (GNJ) scenarios. Based on the time switching (TS) architecture at the relay, the data transmission is...

–Missile borne Monopulse receivers invariably track the target in three domains, namely frequency, range and angle. For effective jamming of these receivers, it is essential that breaking of the track should be achieved in at least two domains. In frequency domain, so long as the monopulse receiver locks onto the radar echo frequency, the radar tracks the target. When there is a disturbance int...

In this paper we consider blind interference suppression in direct sequence spread spectrum communication system with co-existing continuous wave (CW) jammer. Especially, blind source separation techniques are utilized. However, unlike in recent works only a single antenna element is employed. Numerical examples are given to illustrate achieved performance gains.
