Performance analysis for truncated ARQ based DSFBC-CO-OFDM communication scheme
(
IEEE
, 2011 , Conference Paper)
We develop and analyze an ARQ (Automatic Repeat reQuest) based distributed space-frequency block code-orthogonal frequency division multiplexing protocol for cooperative communications (DSFBC-CO-OFDM). At PHY layer, space ...
Performance analysis of relay selection schemes in OFDM-based underlay cognitive networks
(
IEEE
, 2013 , Conference Paper)
Cognitive radio (CR) is a promising technology that allows wireless systems to sense the environment and learn from previous experience to improve the communication quality. However, CR needs a flexible and adaptive physical ...
Performance analysis of selective cooperation in amplify-and-forward relay networks over identical Nakagami-m channels
(
Wiley Online Library
, 2013 , Article)
In cooperative communications, multiple relays between a source and a destination can increase the diversity gain. Because all the nodes must use orthogonal channels, multiple-relay cooperation becomes spectrally inefficient. ...
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 ...
Performance analysis of relay selection schemes in underlay cognitive networks with Decode and Forward relaying
(
IEEE
, 2012 , Conference Paper)
In underlay cognitive networks with regenerative relaying, secondary users operating with primary user are adhering to stringent interference constraint which limits their transmission power and coverage area. In order not ...
Performance analysis of relay selection schemes in underlay cognitive networks with imperfect channel state information
(
IEEE Computer Society
, 2013 , Conference Paper)
Cognitive Radio (CR) aims to improve spectrum utilization by allowing unlicensed users to access the licensed spectrum and to coexist with primary user (PU) while respecting the PU's restrictions. An interesting case to ...
Secrecy Performance Analysis of Multi-Antenna NOMA System with AF/DF relaying under External and Internal Eavesdropping Scenarios
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Due to the successive interference cancellation (SIC) technique, Non orthogonal multiple Access (NOMA) users have the capability of decoding the other paired users sharing the same resource bloc. As a result, NOMA technique ...
Area spectral efficiency of underlay cognitive radio transmission over rayleigh fading channels
(
IEEE
, 2013 , Conference Paper)
Cognitive radio is a promising technology to improve the spectrum utilization by allowing the unlicensed (secondary) user share a frequency bandwidth with the licensed (primary) owner under the condition that no harmful ...
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 ...
