Cascaded Channel Estimation for IRS-assisted Mmwave Multi-antenna with Quantized Beamforming
Wenhui Zhang, Jindan Xu, Wei Xu +2
In this letter, we optimize the channel estimator of the cascaded channel in an intelligent reflecting surface (IRS)-assisted millimeter wave (mmWave) multi-antenna system. In this…
