Conformal IRS-Empowered MIMO-OFDM: Channel Estimation and Environment Mapping

Conformal IRS-Empowered MIMO-OFDM: Channel Estimation and Environment Mapping

We consider the channel estimation and environment mapping problems in multiple-input multiple-output orthogonal frequency division multiplexing systems empowered by intelligent reconfigurable surfaces (IRSs). In order to acquire more in-depth environmental information, as well as, to flexibly take...
