Two Enhanced-rate Power Allocation Strategies for Active IRS-assisted Wireless Network
Qiankun Cheng, Rongen Dong, Wenlong Cai +3
Due to its ability of overcoming the impact of double-fading effect, active intelligent reflecting surface (IRS) has attracted a lot of attention. Unlike passive IRS, active IRS sh…
