A novel CRLH transmission Line using Spiral Resonator
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
In this paper, a novel composite right / left handed transmission line structure composed of six double spiral ring resonator is proposed. The proposed transmission line is designed, simulated and fabricated using an ...
Efficient FPGA-based implementation of a novel dual mode spectrum sensing technique
(2013 , Conference Paper)
Cognitive radio networks require an efficient and reliable method of sensing the spectrum. In this paper, we introduce and implement a new dual mode spectrum sensing technique that is based on combining Quickest Detection ...
A novel peak search & save cyclostationary feature detection algorithm
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Spectrum sensing is a key task in any cognitive radio network. On the other hand, a literature survey in this topic shows a lack of implementation and testbeds for spectrum sensing techniques. In this paper, we plot the ...
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 ...
