With the witnessed exponential growth of Internet of Things (IoT) nodes deployment following the emerging applications, multiple variants of technologies have been proposed to handle the IoT requirements. Among the proposed ...
On physical layer security of correlated multiantenna cognitive radio receivers
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference)
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 ...
A Novel Downlink IM-NOMA Scheme
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In the next generations of communication systems, resources' scarcity devolves to a more critical point as a consequence of the expected massive number of users to be served. Furthermore, the users' contradicting requirements ...
A Novel RIS-Assisted Modulation Scheme
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In this work, in order to achieve higher spectrum efficiency, we propose a reconfigurable intelligent surface (RIS)-assisted multi-user communication uplink system. Different from previous work in which the RIS only optimizes ...
