Large-Scale MIMO Relaying Techniques for Physical Layer Security: AF or DF?

12 May 2015 Chen Xiaoming Lei Lei Zhang Huazi Yuen Chau

In this paper, we consider a large scale multiple input multiple output (LS-MIMO) relaying system, where an information source sends the message to its intended destination aided by an LS-MIMO relay, while a passive eavesdropper tries to intercept the information forwarded by the relay. The advantage of a large scale antenna array is exploited to improve spectral efficiency and enhance wireless security... (read more)
