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 ...
Modified QR-D and MMSE PMI selection technique for MIMO closed loop spatial multiplexing in LTE/LTE-advanced
(2013 , Conference Paper)
Limited feedback closed-loop spatial multiplexing evolved as an attractive technique during the development of Multi Input Multi Output (MIMO) in Long Term Evolution (LTE). Spatial multiplexing involves transmitting ...
On the study of field uniformity inside jet engines
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, the field uniformity of axial electric field component inside an anisotropic jet engine environment is analyzed by using Ansys HFSS simulation tool. The standard deviation based approach is used for the ...
Lifetime maximization for greedy selective relay strategies
(2009 , Conference Paper)
In this paper we propose a new algorithm for selective relay strategies with Amplify-and-Forward (AF) relays which improves the relay network lifetime. The lifetime of the relay network is defined as the maximum number of ...
On the statistical distribution of electric field inside jet engines
(2013 , Conference Paper)
Using full wave analysis in 'Ansys HFSS', we obtain the electric field distribution inside a jet engine containing one set of 24 blades due to the excitation provided by a simple Hertzian dipole. Hertzian dipole illuminates ...
Transmit and receive cooperative cognition: Protocol design and stability analysis
(
IEEE Computer Society
, 2013 , Conference Paper)
In this paper, we investigate the stability of a cooperative cognitive system. We propose a cooperative secondary transmitter-receiver system (CSTR), where, the secondary transmitter (ST) and the secondary receiver (SR) ...
Packet relaying control in sensing-based spectrum sharing systems
(2013 , Conference Paper)
Cognitive relaying has been introduced for opportunistic spectrum access systems by which a secondary node forwards primary packets whenever the primary link faces an outage condition. For spectrum sharing systems, cognitive ...
Spectrum-aggregating cognitive multi-antenna user with multiple primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
We investigate a cognitive radio scenario involving a single cognitive transmitter equipped with K antennas sharing the spectrum with M primary users (PUs) transmitting over orthogonal bands. Each terminal has a queue to ...
The Role of 5G/6G Networks in Building Sustainable and Energy-Efficient Smart Cities
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Conference Paper)
Future wireless networks aim to provide high-energy efficiency, high spectral efficiency, low cost, and support a massive number of connected devices in prospect the evolution of Internet of Things (IoT) and smart cities. ...
Underlay cognitive radio: What is the impact of carrier aggregation and relaying on throughput?
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate joint relay selection and optimal power allocation, as a means to maximize the achievable rate of an underlay cooperative cognitive radio with carrier aggregation, taking into account the ...
