Sustainable LSTM-Based Precoding for RIS-Aided mmWave MIMO Systems with Implicit CSI

Po-Heng Chou, Jiun-Jia Wu, Wan-Jen Huang +1

In this paper, we propose a sustainable long short-term memory (LSTM)-based precoding framework for reconfigurable intelligent surface (RIS)-assisted millimeter-wave (mmWave) MIMO…
