3-D Placement Schemes of Multiple UAVs in NFP-based Wireless Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
In this paper, we propose two placement strategies of multiple unmanned aerial vehicles (UAVs) in network flying platform (NFP)-based wireless networks. The first strategy is based on a proposed distributed placement ...
Physical Layer Security Analysis of UAV Based Communication Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, we investigate the communication security in aerial wiretap channels, where a network flying platform (NFP) wishes to send information to a legitimate destination, in the presence of multiple eavesdroppers. ...
Enhancing wireless networks performance through cooperative communications with interference management
(
IEEE
, 2012 , Conference Paper)
Cooperative radio communication has been proposed as an efficient technique to extend coverage and improve throughput in future wireless networks. However, its performance gain is degraded in the presence of co-channel ...
Dynamic optimization of LTE pilot scattering based on channel estimation
(
IEEE
, 2012 , Conference Paper)
A dynamic optimization of the pilot scattering for Long Term Evolution (LTE) downlink system is introduced. This optimization is based on channel parameters estimations to optimize the number of pilots used in the transmission ...
