Efficient DOA Estimation Method for Reconfigurable Intelligent Surfaces Aided UAV Swarm
Peng Chen, Zhimin Chen, Beixiong Zheng +1
The conventional direction of arrival (DOA) estimation methods are performed with multiple receiving channels. In this paper, a changeling DOA estimation problem is addressed in a…
Radio Frequency Fingerprint Identification for LoRa Using Spectrogram and CNN
Guanxiong Shen, Junqing Zhang, Alan Marshall +2
Radio frequency fingerprint identification (RFFI) is an emerging device authentication technique that relies on intrinsic hardware characteristics of wireless devices. We designed…
IEEE 802.11be-Wi-Fi 7: New Challenges and Opportunities
Cailian Deng, Xuming Fang, Xiao Han +5
With the emergence of 4k/8k video, the throughput requirement of video delivery will keep grow to tens of Gbps. Other new high-throughput and low-latency video applications includi…
Uplink-aided High Mobility Downlink Channel Estimation over Massive MIMO-OTFS System
Yushan Liu, Shun Zhang, Feifei Gao +2
Although it is often used in the orthogonal frequency division multiplexing (OFDM) systems, application of massive multiple-input multiple-output (MIMO) over the orthogonal time fr…
Realistic Channel Models Pre-training
Yourui Huangfu, Jian Wang, Chen Xu +5
In this paper, we propose a neural-network-based realistic channel model with both the similar accuracy as deterministic channel models and uniformity as stochastic channel models.…
Multi-user Resource Control with Deep Reinforcement Learning in IoT Edge Computing
Lei Lei, Huijuan Xu, Xiong Xiong +3
By leveraging the concept of mobile edge computing (MEC), massive amount of data generated by a large number of Internet of Things (IoT) devices could be offloaded to MEC server at…
