Deep Learning-Based Radio Map for MIMO-OFDM Downlink Precoding被引量：1
《Journal of Communications and Information Networks》2023年第3期203-211,共9页Wei Wang Bin Yang Wei Zhang 
This work was supported in part by the Key Area Research and Development Program of Guangdong Province under Grant 2020B0101110003;in part by the National Natural Science Foundation of China under Grant 62201309.The associate editor coordinating the review of this paper and approving it for publication was L.Bai。
Radio map is an advanced technology that mitigates the reliance of multiple-input multiple-output(MIMO)beamforming on channel state information(CSI).In this paper,we introduce the concept of deep learning-based radio ...

Doubling Phase Shifters for Efficient Hybrid Precoder Design in Millimeter-Wave Communication Systems被引量：1
《Journal of Communications and Information Networks》2019年第2期51-67,共17页Xianghao Yu Jun Zhang Khaled B.Letaief 
supported in part by the Hong Kong Research Grants Council under Grant No.16210216 and in part by the Alexander von Humboldt Foundation.
Hybrid precoding is a cost-effective approach to support directional transmissions for millimeter-wave(mmWave)communications,but its precoder design is highly complicated.In this paper,we propose a new hybrid precoder...
