Multi-Layer Downlink Precoding for Cloud-RAN Systems Using Full-Dimensional Massive MIMO

IEEE Access, 2018
Full-dimensional (FD) massive multiple-input multiple-output (MIMO) has recently emerged as one of the physical layer enablers of 5G systems. Grounded on prior work on layered precoding, a novel framework for low-complexity multi-layer downlink precoding

Design of fairness-driven RSMA-SDMA precoding

Tongxin xuebao, 2022
In view of the minimum user rate and system fairness when the transmit power was limited, a user access mode selection transmission strategy by joint rate-splitting multiple access (RSMA) and space division multiple access (SDMA) was proposed.The ...

Deep Video Precoding

, 2019
Several groups are currently investigating how deep learning may advance the state-of-the-art in image and video coding. An open question is how to make deep neural networks work in conjunction with existing (and upcoming) video codecs, such as MPEG AVC, HEVC, VVC, Google VP9 and AOM AV1, as well as existing container and transport formats, without ...

Cascaded Deep Neural Network Based Adaptive Precoding for Distributed Massive MIMO Systems [PDF]

Radioengineering
In time-division duplex (TDD) distributed large-scale multiple input multiple output (DM-MIMO) systems, the traditional downlink channel precoding method is used to resist inter-user interference (IUI).
