We study the cooperative secure transmissions in (multiple-input signal-output) MISO vehicular relay networks where the infrastructure node with multiple antennas sends two confidential messages to two legitimate vehicles with only one antenna, respectively. By exploiting the signal superposition and cooperative jamming techniques, the legitimate vehicle near the infrastructure node directly decodes...
To guarantee secure communication of the primary system and efficiently utilize the licensed spectrum, in this paper, we propose a two-path successive relaying and jamming based cooperative transmission (TSRJC) scheme. In TSRJC scheme, two secondary users (SU) successively relay the primary message and jam the primary eavesdropper to confirm secure and reliable transmission of the primary system during...
Adaptive array signal processing is widely used to improve anti-jamming capability for satellite navigation receivers. Robust beamforming approaches based on steering vector uncertainties, which have been proposed in recent years, have better performance than standard minimum variance distortionless response (MVDR) beamformer in space adaptive processing (SAP). In some practice applications, the attitude...
