Abstract

In this work, we present an interference canceler that can enable blue force communications signal reception in the presence of a co-located jamming system. Unlike existing simultaneous transmit and receive (STAR) systems targeted for commercial WiFi, our Joint Analog and Digital Cancellation (JADIC) architecture requires no prior knowledge about the structure of the interfering waveform. Our JADIC system demo will highlight its self configuration capabilities and its ability to suppress 100+ dB of wideband and narrowband jammer energy.
