HIGHLIGHTS
- who: Olga Muu00f1oz and colleagues from the Department of Signal Theory and Communications, Universitat Politu00e8cnica de Catalunya, Barcelona, Spain have published the paper: Robust Precoding for Multi-User Visible Light Communications with Quantized Channel Information, in the Journal: Sensors 2022, 22, 9238. of /2022/
- what: For polyhedric uncertainty regions and positive real channels as is the case of VLC channels the authors show that the robust precoder against channel quantization errors that minimizes the transmitted optical power while guaranteeing a target signal to noise plus interference ratio (SNIR) per user is the solution of a . . .
