Channel-Estimation-Free Beamforming for RIS-Assisted Systems with Limited Feedback

In this article, we consider received-power maximization in RIS-assisted wireless links using only limited received signal strength (RSS) feedback, avoiding explicit estimation of the high-dimensional cascaded channel. We propose stochastic and deterministic algorithms for passive and active beamforming. In the determi...
