Enhancing wireless networks performance through cooperative communications with interference management
(
IEEE
, 2012 , Conference Paper)
Cooperative radio communication has been proposed as an efficient technique to extend coverage and improve throughput in future wireless networks. However, its performance gain is degraded in the presence of co-channel ...
Performances analysis of SEC based transmit diversity systems with MRC receivers
(
IEEE
, 2012 , Conference Paper)
Switch and Examine combining (SEC) diversity scheme is one of the simplest yet efficient diversity schemes. Earlier in [1] and [2], we proposed sequential power loading algorithm to reduce the average power used at the ...
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, ...
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 ...
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 ...
