Adaptive modulation in multi-user cognitive radio networks over fading channels
(
IEEE Computer Society
, 2013 , Conference Paper)
In this paper, the performance of adaptive modulation in multi-user cognitive radio networks over fading channels is analyzed. Multi-user diversity is considered for opportunistic user selection among multiple secondary ...
On the design of relay-assisted primary-secondary networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The use of N cognitive relays to assist primary and secondary transmissions in a time-slotted cognitive setting with one primary user (PU) and one secondary user (SU) is investigated. An overlapped spectrum sensing strategy ...
Protocol design and stability analysis of cooperative cognitive radio users
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
A single cognitive radio transmitter-receiver pair shares the spectrum with two primary users communicating with their respective receivers. Each primary user has a local traffic queue, whereas the cognitive user has three ...
User Scheduling in Federated Learning over Energy Harvesting Wireless Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
In this paper, the deployment of federated learning (FL) is investigated in an energy harvesting wireless network in which the base station (BS) is equipped with a massive multiple-input multiple-output (MIMO) system and ...
