Resource Management for Device-to-Device Underlay Communication
Chen Xu, Lingyang Song, Zhu Han
Device-to-Device (D2D) communication is a technology component for LTE-A. The existing researches allow D2D as an underlay to the cellular network to increase the spectral efficien…
Truthful Mechanisms for Secure Communication in Wireless Cooperative System
Jun Deng, Rongqing Zhang, Lingyang Song +2
To ensure security in data transmission is one of the most important issues for wireless relay networks, and physical layer security is an attractive alternative solution to addres…
A Differential Feedback Scheme Exploiting the Temporal and Spectral Correlation
Mingxin Zhou, Leiming Zhang, Lingyang Song +1
Channel state information (CSI) provided by limited feedback channel can be utilized to increase the system throughput. However, in multiple input multiple output (MIMO) systems, t…
Relay Selection for Bidirectional AF Relay Network with Outdated CSI
Hongyu Cui, Rongqing Zhang, Lingyang Song +1
Most previous researches on bidirectional relay selection (RS) typically assume perfect channel state information (CSI). However, outdated CSI, caused by the the time-variation of…
Capacity Analysis of Bidirectional AF Relay Selection with Imperfect Channel State Information
Hongyu Cui, Rongqing Zhang, Lingyang Song +1
In this letter, we analyze the ergodic capacity of bidirectional amplify-and-forward relay selection (RS) with imperfect channel state information (CSI), i.e., outdated CSI and imp…
