Abstract
This demonstration presents a real-time anti-jamming MIMO-OFDM wireless communication system that consists of a transmitter, a receiver, and a high-power wideband radio jammer. The key component of our system is a new PHY design for the receiver, which can mitigate jamming signal and recover the desired signal. We demonstrate using software-defined radio (SDR) USRP devices that OFDM-MIMO wireless communications can be enabled in the face of unknown high-power wideband jamming attacks. We show that our PHY design for the receiver can achieve up to 30 dB jamming cancellation.
