On the position optimization of irs
WebIt is argued that optimizing the IRS position provides a new degree of freedom in the network design and enables extra performance gain and results show that the provided … Webposition and communication QoS, robot trajectory and beamforming at the IRS and access point all need to be optimized. We present a solution that can decouple the two problems by exploiting mm-wave chan-nel characteristics. Then, a closed-form solution is obtained for the beamforming optimization problem,
