Optimal Relay Power Allocation for Amplify-and-Forward Relay Networks with Non-linear Power Amplifiers
Chao Zhang, Pinyi Ren, Jingbo Peng +3
In this paper, we propose an optimal relay power allocation of an Amplify-and-Forward relay networks with non-linear power amplifiers. Based on Bussgang Linearization Theory, we de…
A Multi-Channel Diversity Based MAC Protocol for Power-Constrained Cognitive Ad Hoc Networks
Yichen Wang, Pinyi Ren, Qinghe Du +1
One of the major challenges in the medium access control (MAC) protocol design over cognitive Ad Hoc networks (CAHNs) is how to efficiently utilize multiple opportunistic channels,…
Statistical Delay Control and QoS-Driven Power Allocation Over Two-Hop Wireless Relay Links
Qinghe Du, Yi Huang, Pinyi Ren +1
The time-varying feature of wireless channels usually makes the hard delay bound for data transmissions unrealistic to guarantee. In contrast, the statistically-bounded delay with…
Base-Station Selections for QoS Provisioning Over Distributed Multi-User MIMO Links in Wireless Networks
Qinghe Du, Xi Zhang
We propose the QoS-aware BS-selection and the corresponding resource-allocation schemes for downlink multi-user transmissions over the distributed multiple-input-multiple-output (M…
QoS-Aware Base-Station Selections for Distributed MIMO Links in Broadband Wireless Networks
Qinghe Du, Xi Zhang
We propose the QoS-aware BS-selection schemes for the distributed wireless MIMO links, which aim at minimizing the BS usages and reducing the interfering range, while satisfying di…
