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 ...
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 ...
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, ...
