Statisztikák
"We assume T0 = 1, thus T counts the number of channel estimates."
"For comparison purposes, we consider a scheme wherein the channel is estimated for a set of RIS configurations."
Idézetek
"Reconfigurable intelligent surfaces (RISs) are seen as a key enabling technology for beyond fifth generation (B5G) wireless systems."
"The majority of existing works aim at optimizing the RIS elements individually for real-time communications."
