  Abstract

Satellite communication (SATCOM) system provides seamless global service including the sky, the ocean, disaster zone and war zone through the satellite repeater in space. Thus the SATCOM is a promising solution to enhance the communication reliability. It plays an important role in the network centric warfare (NCW) in military communications. However, the SATCOM channels are vulnerable to a jamming threat. Most conventional research works have focused on jamming nulling in the frequency division multiplexing (FDM) and GPS spread spectrum. This paper proposes a new scheme for detection and filtering of narrow-band jamming in a single carrier system (e.g. DVB-S2). The theoretical analysis is presented as a closed-form formulation according to a false detection probability. A frequency-domain design of notch filter is also proposed by analyzing the effect of inter-symbol interference on signal-to-interference-and-noise ratio. Simulation results show that the analytical results are accurate and the proposed notch filter design is effective for narrow-band jamming attacks.
