Impact and Calibration of Nonlinear Reciprocity Mismatch in Massive MIMO
Rongjiang Nie, Li Chen, Nan Zhao +3
Time-division-duplexing massive multiple-input multiple-output (MIMO) systems estimate the channel state information (CSI) by leveraging the uplink-downlink channel reciprocity, wh…
An End-to-End Block Autoencoder For Physical Layer Based On Neural Networks
Tianjie Mu, Xiaohui Chen, Li Chen +2
Deep Learning has been widely applied in the area of image processing and natural language processing. In this paper, we propose an end-to-end communication structure based on auto…
Hybrid Beamforming Design and Performance with Imperfect Phase Shifters in Multiuser Millimeter Wave Systems
Wendi Wang, Huarui Yin, Xiaohui Chen +1
Hybrid beamforming (HBF) includes analog beamforming with phase shifted array in RF domain and digital beamforming in baseband domain. Phase shifted array is usually made up with a…
Stopping Condition for Greedy Block Sparse Signal Recovery
Yu Luo, Ronggui Xie, Huarui Yin +1
For greedy block sparse recovery where the sparsity level is unknown, we derive a stopping condition to stop the iteration process. Focused on the block orthogonal matching pursuit…
Low complexity resource allocation for load minimization in OFDMA wireless networks
Ying Yang, Marco Moretti, Wenxiang Dong +1
To cope with the ever increasing demand for bandwidth, future wireless networks will be designed with reuse distance equal to one. This scenario requires the implementation of tech…
