Outage performance of OFDM-based relaying systems under IQ imbalance
(
IEEE
, 2013 , Conference Paper)
In the presence of different IQ imbalance (IQI) levels in the different nodes of a cooperative system, it becomes necessary to investigate the effect of each imbalance parameter on the performance. In this contribution, ...
Sequential random selection relaying for energy efficient wireless sensor networks
(
IEEE
, 2010 , Conference Paper)
In a wireless sensor network with relaying capability, intermediate relay nodes are with limited energy budget. To maximize lifetime of relay nodes, selective relay strategies, requiring full channel state information ...
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 ...
Analysis of heterogeneous cellular networks interference with biased cell association using Poisson cluster processes
(
IEEE Computer Society
, 2014 , Conference Paper)
Heterogeneous cellular networks (HetNets) achieve high data rates and coverage gains by distributing small cells over macro-cells based on random user demand. Recently, a novel approach to use stochastic geometry for ...
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 ...
