A hybrid spectrum sensing technique with multiple antenna based on GLRT
(2013 , Conference Paper)Spectrum sensing is the core for any cognitive radio network. Quick detection of the primary user signal allows for higher spectrum efficiency. In this paper, we introduce and implement a new hybrid spectrum sensing technique ... -
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 ... -
DDPG Performance in THz Communications over Cascaded RISs: A Machine Learning Solution to the Over-Determined System
( Institute of Electrical and Electronics Engineers Inc. , 2023 , Article)THz technology is considered a key element in 6G wireless communication because it provides ultra-high bandwidths, considerable capacities, and significant gains. However, wireless systems operating at high frequencies are ... -
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 ... -
Exploiting Spatial Correlations: Group Key Generation for Secure IoT Device Networks
( Institute of Electrical and Electronics Engineers Inc. , 2023 , Conference Paper)With the exponential growth in IoT devices, especially in healthcare systems, where multiple devices are attributed to one person, the need for a secure and effective group secret key (GSK) generation is intrinsic. GSKs ... -
Exploiting spectrum sensing data for key management
( Elsevier B.V. , 2017 , Article)In cognitive radio networks, secondary users (SUs) communicate on unused spectrum slots in the frequency bands assigned to primary users (PUs). Like any other wireless communication system, cognitive radio networks are ... -
A Hardware Based Ricean Fading Radio Channel Simulator
( IEEE Xplore , 2017 , Conference Paper)The rise of the need of fading radio channel simulators is due to time and cost of field tests of wireless communications systems. Growth in the demand for fixed wireless access increases the need for wide area system ... -
Microservice instances selection and load balancing in fog computing using deep reinforcement learning approach
( Elsevier , 2024 , Article)Fog-native computing is an emerging paradigm that makes it possible to build flexible and scalable Internet of Things (IoT) applications using microservice architecture at the network edge. With this paradigm, IoT applications ... -
Optimized Resource and Deep Learning Model Allocation in O-RAN Architecture
( IEEE Computer Society , 2023 , Conference Paper)In the era of 5G and beyond, telecommunication networks tend to move Radio Access Network (RAN) from centralized architecture to a more distributed architecture for greater interoperability and flexibility. Open RAN (O-RAN) ... -
Order Statistics-Based Design of UWB Receivers
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)We propose a non-coherent ultra-wideband (UWB) receiver that leverages a single-sample-per-pulse threshold approach to detect the transmitted symbol and is capable of mitigating the impact of impulse noise. Unlike classical ...
