On physical layer security of correlated multiantenna cognitive radio receivers
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
In limited space scenarios, the antennas in the multiantenna cognitive radio (CR) system are closely spaced and often experience correlation among them. In this work, the secrecy performance of correlated multiantenna CR ...
Cognitive relay-sharing by using hierarchical modulation under interference constraints
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate relay-sharing in cognitive radio (CR) networks to improve the secondary user's (SU's) performance in the presence of interference. It is assumed that the relay is shared simultaneously between ...
Performance analysis of cooperative communication system with feedback delay and channel estimation error
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we investigate the impact of feedback delay and channel estimation error (CEE) on the performance of wireless multi-user decode-and-forward (DF) relay systems in independent and non identically distributed ...
Secrecy Performance of Cooperative NOMA System with Multiple Full-Duplex Relays against Non-Colluding/Colluding Eavesdroppers
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
In 5G and beyond wireless communication net-works, non-orthogonal multiple access (NOMA) and Full-Duplex (FD) techniques are considered as promising key techniques. However, the secrecy in NOMA systems has proven to be ...
Optimal power allocation and relay selection in two-way multi-relay cooperative communication
(2013 , Conference Paper)
In this paper, we investigate the power allocation in two-way multi-relay assisted cooperative network in which the relays operate in decode-and-forward (DF) protocol. In the proposed method for choosing the best relay ...
Secure multiple-mode OFDM with index modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Multiple-mode orthogonal frequency division multiplexing with index modulation (MM-OFDM-IM) is a promising IM technique for OFDM systems to improve the spectral efficiency. In this paper, a secure index and data symbol ...
