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 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 ...
Exact closed form expressions for outage probability of GSC receivers over Rayleigh fading channel subject to self-interference
(
IEEE
, 2010 , Conference Paper)
Previous work on performance analyses of generalized selection combining (GSC) RAKE receivers based on the signal to noise ratio focused on the development of methodologies to derive exact closed-form expressions for various ...
Exact capture probability analysis of GSC receivers over Rayleigh fading channel
(
IEEE
, 2010 , Conference Paper)
For third generation systems and ultrawideband systems, RAKE receivers have been introduced due to the advantage of RAKE receivers which is their ability to combine different replicas of the transmitted signal arriving at ...
Performance analysis of best relay selection scheme for fixed gain cooperative networks in non-identical Nakagami-m channels
(
IEEE
, 2010 , Conference Paper)
Selecting the best relay among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay cooperation. This scheme also achieves the ...
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, ...
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, ...
Interference management schemes with general order statistics and interference constraint for multi-user cooperative wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
In this paper, two cooperative communications schemes with interference management are proposed for multiuser wireless networks. The first scheme (Interference Constraint based Relay Selection (ICRS)) maximizes the received ...
Outage analysis of selective cooperation in underlay cognitive networks with fixed gain relays and primary interference modeling
(
IEEE
, 2012 , Conference Paper)
Selective cooperation is a well investigated technique in non-cognitive networks for efficient spectrum utilization and performance improvement. However, it is still a nascent topic for underlay cognitive networks. Recently, ...
