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…
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…
