Jamming attacks present a major challenge for the physical layer security of wireless systems. Among the large number of existing methods for jamming mitigation, filtering is a simple, yet, promising solution that can be applied for resource- constrained wireless networks. In this paper, a first order complex adaptive narrowband filter has been proposed for use against high-power jamming attacks. The central frequency of this notch filter is adaptively adjustable to match the interfering frequency. This enables the proposed solution to perform efficiently in the presence of a jammer whose frequency varies in fixed or random time periods. The simulation results demonstrate the filter's behaviour and the efficiency of the proposed technique.
