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 ...
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, ...
Reactive relay selection in underlay cognitive networks with fixed gain relays
(
IEEE
, 2012 , Conference Paper)
Best relay selection is a bandwidth efficient technique for multiple relay environments without compromising the system performance. The problem of relay selection is more challenging in underlay cognitive networks due to ...
