Classifications and applications of physical layer security techniques for confidentiality: A comprehensive survey
(IEEE-Inst Electrical Electronics Engineers Inc, 2019)Physical layer security (PLS) has emerged as a new concept and powerful alternative that can complement and may even replace encryption-based approaches, which entail many hurdles and practical problems for future wireless ... -
A hybrid downlink NOMA with OFDM and OFDM-IM for beyond 5G wireless networks
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)In this paper, a hybrid power domain non-orthogonal multiple accessing (NOMA) scheme by the superposition of orthogonal frequency division multiple accessing (OFDM) and index modulated OFDM (OFDM-IM) technologies is presented ... -
Impact of mutual coupling on power-domain non-orthogonal multiple access (NOMA)
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)This paper investigates the impact of mutual coupling (MC) on the achievable sum-rate of power-domain non-orthogonal multiple access (NOMA) system in both uplink (UL) and downlink (DL) transmissions. We assume a single-antenna ... -
NOMA with Index modulation for uplink URLLC through grant-free access
(Institute of Electrical and Electronics Engineers Inc., 2019)This paper proposes non-orthogonal sharing of available resources between latency-critical and latency-tolerant communication for fulfilling tight requirements of ultra-reliable low-latency communication (URLLC) as well ... -
Partial-beam non-orthogonal multiple access (PB-NOMA) with fuzzy clustering
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)This letter proposes a partial-beam non-orthogonal multiple access (PB-NOMA) system for millimeter wave (mmWave) channels. In the proposed system, the user terminals (UT)s partially belong to different user groups and ... -
A secure downlink NOMA scheme against unknown internal eavesdroppers
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)Enhancing security level against potential internal eavesdroppers in Non-Orthogonal Multiple Access (NOMA) has been reported as a serious challenge. In this letter, a novel secure NOMA scheme based on physical-layer security ...
