Compressive Channel Estimation for IRS-Aided Millimeter-Wave Systems via Two-Stage Lamp Network

In millimeter-wave (mmWave) systems aided by intelligent reflecting surfaces (IRSs), accurate channel estimation under low pilot overhead is challenging because of the large number of passive IRS elements. By exploiting the low-rank nature of mmWave channels in the virtual angular domain (VAD) and t…
