Adaptive Network Coding over Cognitive Relay Networks
(
IEEE
, 2013 , Conference Paper)
We consider network coded cooperation for cognitive relay networks. The primary system comprises multiple sources and multiple destinations, whereas the secondary system comprises multiple sources, multiple relays and a ...
A minorization-maximization algorithm for an-based mimome secrecy rate maximization
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We consider the problem of secrecy rate maximization in a multi-input multi-output multi-eavesdropper (MIMOME) wiretap channel and present an exact solution. A general system model with a multi-antenna eavesdropper and a ...
Doppler compensation for D-STBC coded time-varying underwater acoustic channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper we investigate the performance of distributed space-time block coding (D-STBC) orthogonal frequency division multiplexing (OFDM) over underwater acoustic (UWA) channels. In particular, we consider a relaying ...
Doppler compensation for AF two way relaying over time varying UWA channels
(
IEEE
, 2014 , Conference Paper)
In this paper, we consider Doppler compensation for time varying underwater acoustic channels. The underlying system model comprises two sources, S1 and S2, communicating with each other through a relay, R. The transmission ...
Precoded spatial modulation for the wiretap channel with relay selection and cooperative jamming
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We propose in this paper a physical layer security (PLS) scheme for dual-hop cooperative networks in an effort to enhance the communications secrecy. The underlying model comprises a transmitting node (Alice), a legitimate ...
Joint optimization of throughput and delay over PPP interfered relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Future wireless networks are expected to achieve higher data rates and ubiquitous coverage by seamless cooperation among diverse network technologies. However, it also increases the risk of co-channel interference and ...
