Artificial-noise-aided secure transmission over finite-ınput ıntersymbol ınterference channels
(IEEE, 2018-06)We propose an artificial noise (AN) injection strategy for securing communication over finite-input intersymbol interference (lSI) channels. The technique relies on injection of colored noise whose power spectral density ... -
Low complexity precoding for MIMOME wiretap channels based on cut-off rate
(IEEE, 2016)We propose a low complexity transmit signal design scheme for achieving information-theoretic secrecy over a MIMO wiretap channel driven by finite-alphabet inputs. We assume that the transmitter has perfect channel state ... -
On secrecy rate analysis of spatial modulation and space shift keying
(IEEE, 2015)Spatial modulation (SM) and space shift keying (SSK) represent transmission methods for low-complexity implementation of multiple-input multiple-output (MIMO) wireless systems in which antenna indices are employed for data ... -
An overview of physical layer security with finite-alphabet signaling
(Institute of Electrical and Electronics Engineers Inc., 2019)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 decade. The vast majority of the existing ... -
Secrecy rate and harvested energy trade-off for MISO channels with finite-alphabet inputs
(IEEE, 2018-05)We focus on transmit signal design for multiple- input single-output (MISO) wiretap channels with simultaneous wireless information and power transfer (SWIPT). Assuming that the channel inputs are drawn from standard ... -
Secure multi-antenna transmission with finite-alphabet signaling
(Bilkent University, 2017-12)With the ever-growing demand for services that rely on transmission over wireless networks, a challenging issue is the security of the transmitted information. Due to its open nature, wireless communications is prone to ... -
Secure space shift keying transmission using dynamic antenna index assignment
(IEEE, 2017-12)We propose a secure transmission scheme based on space shift keying (SSK) in which the indices associated with the transmit antennas are assigned dynamically according to the channel towards the legitimate receiver. We ... -
Transmit signal design for MIMO wiretap channels with statistical CSI and arbitrary inputs
(IEEE, 2018)We propose transmit optimization techniques for multi-input multi-output (MIMO) wiretap channels with statistical channel state information (CSI) at the transmitter. We consider doubly correlated channels towards the ...
