Outage performance for amplify-and-forward channels with an unauthenticated relay [PDF]
2012 IEEE International Conference on Communications (ICC), 2012 We investigate a relay network where the source can potentially utilize an unauthenticated amplify-and-forward (AF) relay to augment its direct transmission of a confidential message to the destination. Since the relay is unauthenticated, it is desirable to protect the confidential data from it while simultaneously making use of it to increase the ...

Multihop Diversity - A Precious Source of Fading Mitigation in Multihop Wireless Networks [PDF]
, 2011 The concept of multihop diversity is proposed, where all the nodes of a multihop link are assumed to have buffers for temporarily storing their received packets.

NOMA-Based User Cooperation With Incremental Hybrid Forwarding Protocols
IEEE Open Journal of the Communications Society, 2021 In this paper, we investigate the performance of a non-orthogonal multiple access (NOMA) wireless system, in which signal transmission of a far user is assisted by a near user.

Outage-constrained resource allocation in uplink NOMA for critical applications [PDF]
, 2017 In this work, we consider the resource allocation problem for uplink non-orthogonal multiple access (NOMA) networks whose users represent power-restricted but high priority devices, such as those used in sensor networks supporting health and public ...

Outage Probability Analysis for Correlated Sources Transmission over Rician Fading Channels [PDF]
, 2013 In this paper, the outage probability of a Slepian-Wolf transmission system is analysed theoretically. We consider two correlated binary information sequences where bit-flipping model is adopted, where the the information bits of the second source are ...

HUMIDITY EFFECT TO 5G PERFORMANCES UNDER PALEMBANG CHANNEL MODEL AT 28 GHZ
Jurnal Ilmiah SINERGI, 2020 The telecommunication has a tremendous improvement in terms of data rates and bandwidth requiring sufficient frequency allocation and wideband spectrum availability. The millimeter-wave frequency band is one of the solution to these requirements, however

Outage Performance of Cooperative Systems Under IQ Imbalance
IEEE Transactions on Communications, 2014 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 compact approximate outage probability expressions are derived and the effect of the different IQI parameters is analyzed for ...

Partial Equalization for MC–CDMA Systems in Non-Ideally Estimated Correlated Fading [PDF]
, 2010 Multicarrier code-division multiple access (MC–CDMA) can support high data rates in next-generation multiuser wireless communication systems. Partial equalization (PE) is a low-complexity technique for combining the signals of subcarriers to improve the ...
