Wireless transmission with cooperation on demand for slow and fast fading environments
(
IEEE
, 2008 , Conference Paper)
Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the relay chooses to cooperate only if the ...
Adaptive Network Coding over Cognitive Relay Networks
(
IEEE
, 2013 , Conference Paper)
We consider network coded cooperation for cognitive relay networks. The primary system comprises multiple sources and multiple destinations, whereas the secondary system comprises multiple sources, multiple relays and a ...
Joint optimization of throughput and delay over PPP interfered relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Future wireless networks are expected to achieve higher data rates and ubiquitous coverage by seamless cooperation among diverse network technologies. However, it also increases the risk of co-channel interference and ...
Multiple antenna cyclostationary-based detection of primary users with multiple cyclic frequency in Cognitive Radios
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the problem of multiple antenna spectrum sensing by using cyclostationary features of Primary Users (PUs) signals in Cognitive Radios (CRs). We consider the general case of multiple antenna sensing ...
Sub-channels selection schemes with interference management for underlay cognitive networks
(
IEEE
, 2013 , Conference Paper)
Cognitive Radio is a promising concept that offers solution to spectral crowding problem by introducing opportunistic usage of the unoccupied licensed frequency bands. Improving the network capacity and reliability of the ...
A Distributed Approach for Networked Flying Platform Association with Small Cells in 5G+ Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The densification of small cell base stations in a 5G architecture is a promising approach to enhance the coverage area and facilitate the ever increasing capacity demand of end users. However, the bottleneck is an intelligent ...
Performance enhancement of cognitive relay networks using regression functions
(
Institute of Electrical and Electronics Engineers Inc.
