Effective area spectral efficiency metric for decode-and-forward cooperative wireless communications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we introduce a new metric, namely: effective area spectral efficiency (EASE), to quantify the spectral efficiency as well as the spatial properties of decoding and forward (DF) relaying wireless communications ...
Capacity analysis of cognitive wireless networks with dynamic spectrum access
(
IEEE Computer Society
, 2015 , Conference Paper)
Cognitive radio (CR) is a promising technology based on spectrum sharing where the secondary unlicensed users can access the licensed frequency bands in the primary system without any modification to the devices, services ...
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 ...
Relay assignment in network-coded cooperative systems with M-PSK modulation over asymmetric channels
(
IEEE
, 2010 , Conference Paper)
We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ...
Priority-based scheduling for limited energy cognitive relaying
(
IEEE
, 2010 , Conference Paper)
We study the problem of cognitive relaying with limited-energy constraint in opportunistic spectrum access cognitive networks. Under this network setting, the cognitive user increases the spectrum availability for its own ...
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 ...
Systemic framework of competencies of 21st century technical and engineering human resource: A development case for a knowledge based Economy in Qatar
(
IEEE
, 2013 , Conference Paper)
The required talent of 21st century engineering and technology human resource is significantly different and more complex than what has been needed ever before. Numerous relevant studies have been conducted during the last ...
Performance analysis of OFDMA based wireless cooperative networks with interference management
(
IEEE
, 2013 , Conference Paper)
In this paper, two cooperative communications schemes with interference management are proposed for orthogonal frequency division multiple access (OFDMA) based wireless networks. The first scheme maximizes the received ...
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 ...
