Cellular communications and networks are particularly vulnerable to eavesdropping attacks due to the opened and broadcasting nature of wireless channels. Due to the rapid development of cellular networks and wireless business, the security issue has attracted a lot of attention. Physical layer security takes the advantages of channel randomness nature of transmission media to achieve communication confidentiality, which is the most important and interesting topic of privacy communication technologies. Artificial noise (AN) or jamming signals with MIMO technologies are supposed to implement physical layer security and enhance secrecy capacities in cellular networks, where AN signals along with confidential data confuse potential eavesdroppers via utilizing orthogonal spaces provided by transmit antennas. In these AN-based schemes, message streams were sent in a multiplexing mode via all eigen-subchannels (positive...
