Outage optimal resource allocation for two-hop multiuser multirelay cooperative communication in OFDMA upstream
(
IEEE
, 2011 , Conference Paper)
We investigate an outage optimal adaptive resource allocation scheme for the upstream of two-hop OFDMA based decode-and-forward cooperative relay systems. The objective of this work is to design resource allocation strategy, ...
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 ...
Lifetime maximization for greedy selective relay strategies
(2009 , Conference Paper)
In this paper we propose a new algorithm for selective relay strategies with Amplify-and-Forward (AF) relays which improves the relay network lifetime. The lifetime of the relay network is defined as the maximum number of ...
Underlay cognitive radio: What is the impact of carrier aggregation and relaying on throughput?
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate joint relay selection and optimal power allocation, as a means to maximize the achievable rate of an underlay cooperative cognitive radio with carrier aggregation, taking into account the ...
