5G wireless backhaul networks: Challenges and research advances
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
5G networks are expected to achieve gigabit-level throughput in future cellular networks. However, it is a great challenge to treat 5G wireless backhaul traffic in an effective way. In this article, we analyze the wireless ...
A hardware implementation for efficient spectrum access in cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Opportunistic spectrum access is a propitious technique to overcome the under-utilization of spectrum bands. In this work, we design an experimental test-bed for evaluating an un-slotted spectrum access scheme under real ...
Optimized collaborative spectrum sensing in energy harvesting cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time and energy resources in energy harvesting cognitive radio (CR) networks. The frame structures for sensing and ...
Novel cooperative policy for cognitive radio networks: Stability region and delay analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We consider a cognitive radio system that consists of primary user, secondary user, and their destinations. The secondary user has a relaying capability, i.e., it transmits the relayed packets from the primary user. Unlike ...
