Improved relay selection for decode-and-forward cooperative wireless networks under secrecy rate maximization
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)Privacy and security have an increasingly important role in wireless networks. A secure communication enables a legitimate destination to successfully retrieve information sent by a source, while it disables the eavesdropper ... -
Inter-relay interference cancellation for wireless multi-user multi-decode-and-forward relay networks
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, a cooperative communication scheme with inter-relay interference (IRI) cancellation is proposed for wireless multi-user multi-decode-and-forward (DF) relay networks. The scheme is based on a DF half-duplex ... -
Inter-relay Interference management schemes for multi-user cooperative wireless networks
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)In this paper, two cooperative communications schemes with inter-relay interference (IRI) management are proposed for multi-user wireless networks. The first scheme (Interference management at relay station (IMR)) uses the ... -
Interference management schemes for multi-user cooperative wireless networks
( John Wiley and Sons Ltd , 2016 , Article)Cooperative communication is a promising technique for future wireless networks. It can be used in improving communication reliability and enhancing spectrum efficiency by using the broadcast nature of radio communication ... -
Joint optimal threshold-based relaying and ml detection in network-coded two-way relay channels
( Institute of Electrical and Electronics Engineers Inc. , 2012 , Article)In this paper, we address the problem of joint optimal threshold-based relaying and maximum likelihood (ML) detection in network-coded cooperative systems. The purpose of using threshold-based relaying is to circumvent the ... -
Outage performance of cooperative systems under IQ imbalance
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)In this contribution, we investigate the outage performance of OFDM-based Decode and Forward (DF), Amplify and Forward (AF) and Controlled DF (CDF) cooperative systems under IQ Imbalance (IQI). In particular, tractable and ... -
Outage performance of incremental relaying networks with OFDM subcarriers mapping schemes
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)The scarcity of radio resources coupled with the high data rate demands in the last few years, induced incremental relaying techniques one of the most promising technologies. This is simply because it allows reaping spatial ... -
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, ... -
Performance analysis of cooperative communication system with feedback delay and channel estimation error
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, we investigate the impact of feedback delay and channel estimation error (CEE) on the performance of wireless multi-user decode-and-forward (DF) relay systems in independent and non identically distributed ...
