Transformer-Based Precoding for User-Centric Network Massive MIMO Optical Wireless Communications

IEEE Access
Multiple-input multiple-output (MIMO) optical wireless communications (OWC) is a key technology to meet the growing demand for high data rates and reliable connectivity in sixth-generation (6G) wireless communications.

Efficient Constant Envelope Precoding for Massive MU-MIMO Downlink via Majorization-Minimization Method

Entropy
The practical implementation of massive multi-user multi-input–multi-output (MU-MIMO) downlink communication systems power amplifiers that are energy efficient; otherwise, the power consumption of the base station (BS) will be prohibitive.
