Two-Stage Channel Estimation for Semi-Passive RIS-Assisted Millimeter Wave Systems

In a reconfigurable intelligent surface (RIS) assisted millimeter Wave (mmWave) communication system, the channel coefficient increases exponentially with the number of RIS elements which results in expensive pilot overhead. Most previous works have proposed some channel estimation algorithms for th...
