Partial relay selection in underlay cognitive networks with fixed gain relays
(
IEEE
, 2012 , Conference Paper)
In a communication system with multiple cooperative relays, selecting the best relay utilizes the available spectrum more efficiently. However, selective relaying poses a different problem in underlay cognitive networks ...
Relay selection for cooperative underwater acoustic communication systems
(
IEEE
, 2012 , Conference Paper)
In this paper, we consider a multi-carrier and multi-relay underwater acoustic communication (UWAC) system and investigate the relay selection problem. Our channel model is built on an aggregation of both large-scale path ...
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 ...
A diversity compression and combining technique based on channel shortening for cooperative networks
(
IEEE
, 2012 , Article)
The cooperative relaying process with multiple relays needs proper coordination among the communicating and the relaying nodes. This coordination and the required capabilities may not be available in some wireless systems ...
Area spectral efficiency of cooperative network with opportunistic relaying
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate the area spectral efficiency (ASE) in a three-node cooperative network with opportunistic relaying. On one hand, in conventional cellular network, ASE is defined to be the average data rate ...
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, ...
Optimized Selective OFDMA in multihop network
(
IEEE
, 2012 , Conference Paper)
Selective OFDMA is a powerfull relaying technique with subcarrier based selection. This scheeme has a high potential to considerably improve the performance of cooperative OFDM systems. However, in practice, the implementation ...
Area spectral efficiency of cooperative network with DF and AF relaying
(
IEEE
, 2012 , Conference Paper)
Most performance metrics for cooperative networks focus on the qualification of either spectrum efficiency or link reliability, without considering the spatial effect of radio transmission. Area spectral efficiency (ASE) ...
Performance of two way opportunistic MAC protocol in non-saturated ad hoc networks
(
IEEE
, 2012 , Conference Paper)
In this paper, performance of relay based MAC protocol for two way traffic is evaluated in non-saturated condition. In real life, non-saturation is more prevalent where nodes are mostly idle. The idea of Two Way ...
Joint optimal threshold-based relaying and ml detection in network-coded two-way relay channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2012 , Article)
In this paper, we address the problem of joint optimal threshold-based relaying and maximum likelihood (ML) detection in network-coded cooperative systems. The purpose of using threshold-based relaying is to circumvent the ...
