An LSTM-MADDPG Framework for Joint Beamforming Control in STAR-RIS-Assisted Cell-Free Massive MIMO Network

Conventional reconfigurable intelligent surfaces (RIS)-aided cell-free massive multiple-input multiple-output (CF mMIMO) networks are inherently constrained by half-space reflection, which limits coverage expansion and flexible deployment. To overcome this issue, simultaneously transmitting and reflecting reconfigurabl...
