Randomized Control of Wireless Temporal Coherence Via Reconfigurable Intelligent Surface
A reconfigurable intelligent surface (RIS) can shape the wireless propagation channel by inducing controlled phase shift variations to the impinging signals. Multiple works have considered the use of RIS with time-varying configurations of reflection coefficients. In this work, we use the RIS to control the channel coherence time and introduce …
