Providing secure communications over the physical layer with the objective of achieving
secrecy without requiring a secret key has been receiving growing attention within the past …

Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a recently
developed transmission technique that extends the principle of spatial modulation to OFDM …

The explosive increase of mobile data services and the use of smart phones require the fifth
generation (5G) network to support higher spectral efficiency, higher energy efficiency, and …

In this paper, we investigate the secrecy rate of finite-alphabet communications over multiple-
input-multiple-output-multiple-antenna eavesdropper (MIMOME) channels. Traditional …

The application of hybrid precoding in millimeter wave (mm-wave) multiple-input multiple-
output (MIMO) systems has been proven effective for reducing the number of radio …

Modern wireless channels are increasingly dense and mobile making the channel highly
non-stationary. The time-varying distribution and the existence of joint interference across …

Optimal power allocation for orthogonal frequency division multiplexing (OFDM) wiretap
channels with Gaussian channel inputs has already been studied in some previous works …

Multiple antennas have played an essential role in spatial multiplexing and diversity
transmission for a wide range of communication applications. Most advances in the design …

In this paper, we investigate secure transmission over the large-scale multiple-antenna
wiretap channel with finite alphabet inputs. First, we investigate the case where …

We propose and investigate a full-duplex receiver assisted secure spatial modulation (FDR-
SSM) scheme, whose security is enhanced by the jamming sent from a full-duplexing legal …
