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 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, ...
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 ...
Power loading algorithms for SEC diversity schemes
(
IEEE
, 2007 , Conference Paper)
Switch and Examine Combing (SEC) diversity scheme is one of the simplest diversity schemes to combat fading. When the power used for probing the channels in this scheme is fixed, it can be higher than what is actually ...
Capacity enhancement in cognitive radio wireless network with dynamic spectrum access
(
IEEE Computer Society
, 2014 , Conference Paper)
Deployment of femto-cells underlaying the macro-cell has been proven to greatly improve the system capacity and the indoor coverage. However, to successfully deploy this heterogeneous network, the interference among the ...
Secure Performance Analysis for Full-Duplex Cooperative NOMA System in the Presence of Multiple Eavesdroppers
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
This paper investigates the physical layer security of a full-duplex (FD) Decode-and-Forward (DF) NOMA network assumed to undergo independent and identically distributed Nakagami-m fading. Herein, we provide a secrecy ...
Secrecy Performance Analysis of Cooperative NOMA system with multiple DF Relays
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
In this paper, we derive the Secrecy Outage Probability (SOP) and Strictly Positive Secrecy Capacity (SPSC) of cooperative Non Orthogonal Multiple Access (NOMA) in the presence of K Decode and Forward (DF) relays and ...
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 ...
Design and Implementation of Cadastral Geo-spatial IoT Network Gateway Analyzer for Urban Scale Infrastructure Health Monitoring
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Urban and global scale health monitoring systems have gained significance in digital ecosystems. Every stakeholder is striving for efficiency through performance analysis of digital infrastructure health monitoring (IHM) ...
