Cellular Communications on License-Exempt Spectrum: A Tutorial
Binyin Ren, Mao Wang, Jingjing Zhang +3
A traditional cellular system (e.g., LTE) operates only on the licensed spectrum. This tutorial explains the concept of cellular communications on both licensed and license-exempt…
Power- and Spectrally-Efficient Network Access for Cellular Machine-Type Communications
Wenjie Kristo Yang, Mao Wang, Jun Kingsley Zou +2
Machine-type communication (MTC) is the key technology to support data transfer among devices (sensors and actuators). Cellular communication technologies are developed mainly for…
Analysis of the Frequency Offset Effect on Zadoff-Chu Sequence Timing Performance
Min Hua, Kristo W. Yang, M. Wang +1
Zadoff-Chu (ZC) sequences have been used as synchronization sequences in modern wireless communication systems, replacing the conventional pseudo-random noise (PN) sequences due to…
Discovery Signal Design and Its Application to Peer-to-Peer Communications in OFDMA Cellular Networks
Michael. Wang, C. Jiang
This paper proposes a unique discovery signal as an enabler of peer-to-peer (P2P) communication which overlays a cellular network and shares its resources. Applying P2P communicati…
