Achievable Rate Lower Bound and Bottleneck Analysis for IRS-Assisted MISO Systems With Channel Estimation Errors
Intelligent reflecting surfaces (IRSs) have attracted extensive research interest for their passive beamforming gains. However, practical IRS-assisted systems rely heavily on accurate channel state information (CSI), which inevitably suffers from estimation errors. Motivated by this challenge, we first investigate the...
