The proposed JASS method enables reliable time synchronization in the MIMO uplink while mitigating smart jamming attacks through adaptive spatial filtering.
บทคัดย่อ
The paper proposes JASS, a method for jammer-resilient time synchronization in the MIMO uplink. Key highlights:
JASS detects a randomized synchronization sequence by fitting a spatial filter to the time-windowed receive signal to mitigate the jammer interference.
JASS is proven to successfully detect the synchronization sequence under certain intuitive conditions, even in the presence of smart jammers.
An efficient algorithm is derived to approximately solve the JASS optimization problem.
Simulations demonstrate the effectiveness of JASS against a wide range of jammer types, including smart multi-antenna jammers that dynamically change their behavior.
JASS does not require any explicit information about the jammer's type or behavior, making it a universal solution for jammer mitigation.
สถิติ
The paper does not contain any explicit numerical data or statistics to support the key claims. The performance of the proposed JASS method is evaluated through simulations.
