A Dimension Reduction-Based Joint Activity Detection and Channel Estimation Algorithm for Massive Access
Xiaodan Shao, Xiaoming Chen, Rundong Jia
Grant-free random access is a promising protocol to support massive access in beyond fifth-generation (B5G) cellular Internet-of-Things (IoT) with sporadic traffic. Specifically, i…
Deep Learning for Spectrum Sensing
Jiabao Gao, Xuemei Yi, Caijun Zhong +2
In cognitive radio systems, the ability to accurately detect primary user's signal is essential to secondary user in order to utilize idle licensed spectrum. Conventional energy de…
MmWave Communication With Active Ambient Perception
Chunxu Jiao, Zhaoyang Zhang, Caijun Zhong +2
In existing communication systems, the channel state information of each UE (user equipment) should be repeatedly estimated when it moves to a new position or another UE takes its…
Design of Non-Orthogonal Beamspace Multiple Access for Cellular Internet-of-Things
Rundong Jia, Xiaoming Chen, Caijun Zhong +3
In this paper, we study the problem of massive connections over limited radio spectrum for the cellular Internet-of-Things (IoT) in the fifth-generation (5G) wireless network. To a…
