We address the challenging problem of channel estimation in a narrowband multiuser communication that in-corporates intelligent reflecting surfaces (IRS). To overcome the limitations of the two-hop channel in passive IRS system, we adopt a Hybrid IRS architecture, which involves integrating active s...
