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 ...
Secure Communications Using Directional Modulation
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Limitations on the wireless communication resources (i.e., time and frequency) introduces the need for another domain that can help communication systems to match the increasing demand on high data transfer rates and quality ...
Adaptive hierarchical cooperative communication using energy harvesting relay
(2013 , Conference Paper)
In this paper, we present an adaptive wireless communication system with energy harvesting relay where, two sources wish to send data to a destination via an energy harvesting relay that utilizes hierarchical constellation. ...
Multiuser scheduling on downlink communications by using adaptive hierarchical modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a novel downlink system that is able to maximize the number of users which could be served with high correct decoding probability while, minimizing the total consumed energy for data reconstruction ...
