Exploiting Large-Scale MIMO Techniques for Physical Layer Security with Imperfect Channel State Information
Xiaoming Chen, Chau Yuen, Zhaoyang Zhang
In this paper, we study the problem of physical layer security in large-scale multiple input multiple output (LS-MIMO) systems. The large number of antenna elements in LS-MIMO syst…
Distributed Spectrum-Aware Clustering in Cognitive Radio Sensor Networks
Huazi Zhang, Zhaoyang Zhang, Huaiyu Dai +2
A novel Distributed Spectrum-Aware Clustering (DSAC) scheme is proposed in the context of Cognitive Radio Sensor Networks (CRSN). DSAC aims at forming energy efficient clusters in…
Energy Efficient Joint Source and Channel Sensing in Cognitive Radio Sensor Networks
Huazi Zhang, Zhaoyang Zhang, Xiaoming Chen +1
A novel concept of Joint Source and Channel Sensing (JSCS) is introduced in the context of Cognitive Radio Sensor Networks (CRSN). Every sensor node has two basic tasks: applicatio…
