Pilot-Efficient Channel Estimation for RIS-Aided Wireless Communication Systems: A Systematization

Passive reconfigurable intelligent surfaces (RIS) can reshape the propagation environment with negligible radio-frequency power, yet they introduce a dominant channel-acquisition bottleneck, because the cascaded channel to be learned is high-dimensional and its naive pilot cost scales with the numbe...
