CSI-Secured Orthogonal Jamming Method for Wireless Physical Layer Security

In this paper, we propose a new cooperative jamming (CJ) method to prevent eavesdroppers from using beam-formers to suppress the jamming signals. In this method, the broadcasting of system-node channel state information (CSI) is first averted. The transmitting and jamming signals are then aligned in...

Description
Summary:In this paper, we propose a new cooperative jamming (CJ) method to prevent eavesdroppers from using beam-formers to suppress the jamming signals. In this method, the broadcasting of system-node channel state information (CSI) is first averted. The transmitting and jamming signals are then aligned in two separate single dimensions in complex space. The decode-and-forward relaying protocol is employed.The proposed method is more effective than current CJ techniques.
