Ergodic Capacity Comparison of Different Relay Precoding Schemes in Dual-Hop AF Systems with Co-Channel Interference
Guangxu Zhu, Caijun Zhong, Himal A. Suraweera +3
In this paper, we analyze the ergodic capacity of a dual-hop amplify-and-forward relaying system where the relay is equipped with multiple antennas and subject to co-channel interf…
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…
