Improved relay selection for decode-and-forward cooperative wireless networks under secrecy rate maximization
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Privacy and security have an increasingly important role in wireless networks. A secure communication enables a legitimate destination to successfully retrieve information sent by a source, while it disables the eavesdropper ...
Performance analysis of best relay selection scheme for amplify-and-forward cooperative networks in identical Nakagami-m channels
(
IEEE
, 2010 , Conference Paper)
In cooperative communication networks, the use of multiple relays between the source and the destination was proposed to increase the diversity gain. Since the source and all the relays must transmit on orthogonal channels, ...
Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
(
IEEE
, 2011 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the area of coverage. Therefore, it is ...
Inter-relay interference cancellation for wireless multi-user multi-decode-and-forward relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, a cooperative communication scheme with inter-relay interference (IRI) cancellation is proposed for wireless multi-user multi-decode-and-forward (DF) relay networks. The scheme is based on a DF half-duplex ...
Performance analysis of cooperative communication system with feedback delay and channel estimation error
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we investigate the impact of feedback delay and channel estimation error (CEE) on the performance of wireless multi-user decode-and-forward (DF) relay systems in independent and non identically distributed ...
Secret key generation based on AoA estimation for low SNR conditions
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In the context of physical layer security, a physical layer characteristic is used as a common source of randomness to generate the secret key. Therefore an accurate estimation of this characteristic is the core for reliable ...
Outage performance of OFDM-based relaying systems under IQ imbalance
(
IEEE
, 2013 , Conference Paper)
In the presence of different IQ imbalance (IQI) levels in the different nodes of a cooperative system, it becomes necessary to investigate the effect of each imbalance parameter on the performance. In this contribution, ...
Distributed interference management using Q-Learning in cognitive femtocell networks: New USRP-based implementation
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Femtocell networks have become a promising solution in supporting high data rates for 5G systems, where cell densification is performed using the small femtocells. However, femtocell networks have many challenges. One of ...
Estimating the number of sources: An efficient maximization approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Estimating the number of sources received by an antenna array have been well known and investigated since the starting of array signal processing. Accurate estimation of such parameter is critical in many applications that ...
Modeling and analysis of HetNet interference using Poisson Cluster Processes
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Future mobile networks are converging towards being heterogeneous, owing to the co-existence of multi-tier networks within the same geographical area, including macro, pico- and femto-cells. The deployment of such networks ...
