Autor: Nhu Tri Do, Beongku An

Publikováno v: Sensors, Vol 15, Iss 2, Pp 4388-4407 (2015)

In this paper we propose a soft-hard combination scheme, called SHC scheme, for cooperative spectrum sensing in cognitive radio networks. The SHC scheme deploys a cluster based network in which Likelihood Ratio Test (LRT)-based soft combination is ap

Performance Analysis of Physical Layer Security of Opportunistic Scheduling in Multiuser Multirelay Cooperative Networks

Autor: Kyusung Shim, Nhu Tri Do, Beongku An

Publikováno v: Sensors, Vol 17, Iss 2, p 377 (2017)

In this paper, we study the physical layer security (PLS) of opportunistic scheduling for uplink scenarios of multiuser multirelay cooperative networks. To this end, we propose a low-complexity, yet comparable secrecy performance source relay selecti

In this paper, we study physical layer security (PLS) of wireless networks in presence of one eavesdropper. Assume that the channel state information (CSI) of the eavesdropper cannot be obtained at the transmitter, such as CSI can be then estimated t

In this paper, we analyze the downlink outage performance of opportunistic scheduling in dual-hop cooperative networks consisting of one source, multiple radio-frequency energy harvesting relays, and multiple destinations. To this end, two low-comple
