Cognitive Heterogeneous Networks with Unreliable Backhaul Connections
Mobile Networks and Applications, 2017To 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 Cooperative Systems With Unreliable Backhauls and Selection Combining
IEEE Transactions on Vehicular Technology, 2017In 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 ...

Robust Communication via Decentralized Processing With Unreliable Backhaul Links
IEEE Transactions on Information Theory, 2011A 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 Wireless Networks With Unreliable Backhaul Links
IEEE Communications Letters, 2015A cooperative wireless network, where a cluster of $K$ single-antenna transmitters jointly serve a single-antenna receiver, is considered. Each transmitter is connected to the control unit (CU) via independent but unreliable backhaul links. The CU sends a common message to each transmitter over backhaul links, which upon successful reception ...

Secure communication via an untrusted relay with unreliable backhaul connections
Wireless Networks, 2019This paper studies the secrecy performance of a wireless energy harvesting system in which a source connected to wireless backhaul links sends information to a destination via an untrusted relay that not only helps the overall commutation but also overhears the sources confidential information.

Outage probability of finite-sized selective relaying systems with unreliable backhauls
2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017Considering 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

Performance Analysis of Finite-Sized Co-Operative Systems With Unreliable Backhauls
IEEE Transactions on Wireless Communications, 2016This 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)

Opportunistic relaying for cooperative small-cell systems with unreliable wireless backhauls
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018In 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.

Secrecy Performance of Cooperative Single Carrier Systems with Unreliable Backhaul Connections
2016 IEEE Global Communications Conference (GLOBECOM), 2016In 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.
