Mitigating Smart Jammers in MU-MIMO via Joint Channel Estimation and Data Detection

Mitigating Smart Jammers in MU-MIMO via Joint Channel Estimation and Data Detection

Wireless systems must be resilient to jamming attacks. Existing mitigation methods require knowledge of the jammer's transmit characteristics. However, this knowledge may be difficult to acquire, especially for smart jammers that attack only specific instants during transmission in order to evade mitigation. We propose a novel method that mitigates attacks …
