When headlines blared that ballet flats were back in style, my initial thought was: They ever weren’t?! I’ve been rocking the ...

Abstract: An enhanced codebook generation approach based only on precoding matrix indicator (PMI) feedback information is proposed. By utilizing the kernel density estimation (KDE) to produce ...

However, phase shifter adjustments in STAR-RIS are limited by coupling constraints. We introduce a codebook design for phase-shift adjustment that accounts for these constraints. Leveraging this ...
