Compressed Channel Estimation for Intelligent Reflecting Surface-Assisted Millimeter Wave Systems

In this letter, we consider channel estimation for intelligent reflecting surface (IRS)-assisted millimeter wave (mmWave) systems, where an IRS is deployed to assist the data transmission from the base station (BS) to a user. It is shown that for the purpose of joint active and passive beamforming,...
