Abstract

The mitigation of in-band interference from co-located emitters is an increasingly important problem in commercial and military wireless communications systems design. In this work, we present a co-located interference mitigation approach that is targeted for scenarios in which the interfering signal is received at an extremely high power and the delay between the received (over-the-air) and reference (wired) copies of the interferer is not negligible. Such scenarios are common in military applications (e.g., simultaneous jamming and communications). The proposed Joint Analog and Digital Interference Cancellation (JADIC) system is self-configuring and can provide over 100 dB of suppression of wideband and narrowband jammers.
