A Deep Learning Model for LoRa Signals Classification Using Cyclostationay Features
(
IEEE Computer Society
, 2021 , Conference Paper)
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 ...
SFET-based multiple antenna spectrum sensing using the second order moments of eigenvalues
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a new detector for multiantenna spectrum sensing in cognitive radios (CR) by exploiting the Separating Function Estimation Test (SFET) framework. Specifically, we consider a blind scenario for ...
Energy-Aware Cooperative Wireless Networks with Multiple Cognitive Users
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we study and analyze cooperative cognitive radio networks with arbitrary number of secondary users (SUs). Each SU is considered a prospective relay for the primary user (PU) besides having its own data ...
Capacity enhancement in cognitive radio wireless network with dynamic spectrum access
(
IEEE Computer Society
, 2014 , Conference Paper)
Deployment of femto-cells underlaying the macro-cell has been proven to greatly improve the system capacity and the indoor coverage. However, to successfully deploy this heterogeneous network, the interference among the ...
Band allocation for cognitive radios with buffered primary and secondary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we study band allocation of Ms buffered secondary users (SUs) to Mp orthogonal primary licensed bands, where each primary band is assigned to one primary user (PU). Each SU is assigned to one of the available ...
Partial relay selection in underlay cognitive networks with fixed gain relays
(
IEEE
, 2012 , Conference Paper)
In a communication system with multiple cooperative relays, selecting the best relay utilizes the available spectrum more efficiently. However, selective relaying poses a different problem in underlay cognitive networks ...
Optimal cooperative cognitive relaying and spectrum access for an energy harvesting cognitive radio: Reinforcement learning approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we consider a cognitive setting under the context of cooperative communications, where the cognitive radio (CR) user is assumed to be a self-organized relay for the network. The CR user and the primary user ...
Stability and delay analysis for cooperative relaying with multi-access transmission
(
Springer Verlag
, 2015 , Conference Paper)
We consider a cooperative relaying system with two source terminals, one full duplex relay, and a common destination. Each terminal has a local traffic queue while the relay has two relaying queues to store the relayed ...
Research trends in multi-standard device-to-device communication in wearable wireless networks
(
Springer Verlag
, 2015 , Conference Paper)
Wearable Wireless Networks (WWN) aim to provide attractive alternate for conventional medical care system. It is an effective way of monitoring patients within clinics, hospitals and remotely from home, offices etc. In ...
