PROJECT TITLE :

Jamming Resilient Communication Using MIMO Interference Cancellation

ABSTRACT:

Jamming attack is a serious threat to the wireless communications. Reactive jamming maximizes the attack efficiency by jamming only when the targets are communicating, that will be readily implemented using software-outlined radios. During this paper, we explore the utilization of the multi-input multi-output (MIMO) technology to achieve jamming resilient orthogonal frequency-division multiplexing (OFDM) communication. In particular, MIMO interference cancellation treats jamming signals as noise and strategically cancels them out, while transmit precoding adjusts the signal directions to optimize the decoding performance. We first investigate the reactive jamming strategies and their impacts on the MIMO-OFDM receivers. We tend to then present a MIMO-primarily based anti-jamming theme that exploits MIMO interference cancellation and transmit precoding technologies to flip a jammed non-connectivity state of affairs into an operational network. We implement our jamming resilient communication theme using software-outlined radios. Our testbed analysis shows the destructive power of reactive jamming attack, and additionally validates the efficacy and potency of our defense mechanisms within the presence of diverse types of reactive jammers with totally different jamming signal powers.
