Continuous noise covert transmission scheme based on QCSK

Tongxin xuebao, 2022
The existing embedded scheme requires far lower transmission power of the covert system than that of the host system, and thus decreasing the reliability of covert transmission.To figure out the above limitations, a continuous noise covert communication ...

A Novel Physical Layer Security Scheme in OFDM-Based Cognitive Radio Networks

IEEE Access, 2018
In this paper, a physical-layer-security scheme for an underlay relay-based cognitive radio network (CRN) that uses orthogonal frequency-division multiplexing (OFDM) as the medium access technique is proposed.

Full duplex secret transmission scheme based on user cooperation

Tongxin xuebao, 2017
Full-duplex artificial noise scheme can achieve a limited improvement while the interference power keeps increasing and the full-duplex gain is null.To solve these two problems,a full-duplex secure transmission scheme based on user cooperation was ...

Pilot-Based Codebook Non-Orthogonal Artificial Noise Schemes for Physical Layer Security: Secrecy Capacity Optimization Under Unknown Eavesdropper Channels

IEEE Access
Non-Orthogonal Artificial Noise (NORAN) has garnered significant attention in modern communication systems as a substitute for traditional Artificial Noise (AN), due to its independence from channel degrees of freedom.

Eavesdropping against wireless spatial scrambling secure communication: hyperplane clustering

Tongxin xuebao, 2014
The existing eavesdropping method has poor anti-noise performance and high complexity, which makes it not practical. It is shown that the received scrambled signals are distributed within parallel hyperplanes if adequate antennas are equipped by ...
