Secrecy Performance of Finite-Sized Cooperative Single Carrier Systems With Unreliable Backhaul Connections

IEEE Transactions on Signal Processing, 2016
In this paper, the secrecy performance of finite-sized cooperative cyclic prefixed single carrier systems with multiple eavesdroppers and unreliable wireless backhaul connections across multiple transmitters is investigated. For nonidentical frequency-selective fading channels between the relay and destination nodes, secrecy performance metrics ...

Robust Communication via Decentralized Processing With Unreliable Backhaul Links

IEEE Transactions on Information Theory, 2011
A source communicates with a remote destination via a number of distributed relays. Communication from source to relays takes place over a (discrete or Gaussian) broadcast channel, while the relays are connected to the receiver via orthogonal finite-capacity links.

Performance Analysis of Cooperative Systems With Unreliable Backhauls and Selection Combining

IEEE Transactions on Vehicular Technology, 2017
In this paper, a cooperative wireless system with unreliable wireless backhaul connections is investigated. To increase the throughput and maximize the receiver signal-to-noise ratio (SNR), a selection combining (SC) protocol is employed. Cooperative transmitters are connected to the control unit (CU) via independent but unreliable wireless backhaul ...

Opportunistic relaying for cooperative small-cell systems with unreliable wireless backhauls

2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018
In this paper, we investigate the outage performance of opportunistic relaying for a cooperative small-cell system with M small-cell transmitters and N relays. To enable flexible deployment of ultra dense small-cells, wireless backhauls are applied for connecting a macro-cell base station and M smallcell transmitters.

Outage Probability for Cognitive Heterogeneous Networks with Unreliable Backhaul Connections

2018
To enhance the spectrum scarcity of cooperative heterogeneous networks (HetNets) with unreliable backhaul connections, we examine the impact of cognitive spectrum sharing over multiple small-cell transmitters in Nakagami-m fading channels. In this system, the secondary transmitters are connected to macro-cell via wireless backhaul links and communicate

Performance Analysis of Finite-Sized Co-Operative Systems With Unreliable Backhauls

IEEE Transactions on Wireless Communications, 2016
This paper presents a performance analysis of a finite-sized co-operative wireless system, where a group of transmitters with unreliable backhauls serve a desired receiver using noncoherent joint transmission. To facilitate analysis, an analytical expression for the distribution of the spatially averaged signal-to-interference-plus-noise ratio (SA-SINR)

Secrecy Performance of Finite-Sized In-Band Selective Relaying Systems With Unreliable Backhaul and Cooperative Eavesdroppers

IEEE Journal on Selected Areas in Communications, 2018
This paper investigates the secrecy performance of a finite-sized in-band selective relaying system with $M$ transmitters connected via unreliable backhaul links, $N$ decode-and-forward relays, and $K$ collaborative eavesdroppers. To send the source message to the destination, a transmitter-relay pair that achieves the highest end-to ...

Outage probability of finite-sized selective relaying systems with unreliable backhauls

2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017
Considering unreliable wireless backhaul connections across transmitters, we investigate the outage performance of a finite-sized selective relaying system with M transmitters and N relays under Nakagami-m fading channels. To send the source message to the destination, the transmitter-relay pair providing the highest end-to-end signal-to-noise ratio is

Secrecy Performance of Cooperative Single Carrier Systems with Unreliable Backhaul Connections

2016 IEEE Global Communications Conference (GLOBECOM), 2016
In this paper, the secrecy outage probability of cooperative cyclic prefixed single carrier (CP-SC) systems with multiple transmitters and unreliable backhaul connections is derived. The transmitters communicate with the destination in the presence of an eavesdropper over two-hop relay channels with non-identical frequency-selective fading.

Cooperative Cognitive Non-Orthgonal Multiple Access Under Unreliable Backhaul Connections

Mobile Networks and Applications, 2018
In this paper, we investigate the performance of energy-harvesting communications with decode-and-forward relay in the presence of non-orthogonal multiple access (NOMA) multiple access and cognitive radio spectrum sharing. We study three cases of single transmitter single relay and various transmitters and relays with two selection strategies (called ...
