Reconfigurable Intelligent Surfaces Aided Communication: Capacity and Performance Analysis Over Rician Fading Channel
Abstract
In this work, we consider a single input single output (SISO) system for Reconfigurable Intelligent Surface (RIS) assisted mmWave communication. We consider Rician channel models over user node to RIS and RIS to Access Point (AP). We obtain closed form expressions for capacity with channel state information (CSI) and without CSI at the transmitter. Newly derived capacity expressions are closed form expressions in a very compact form. We also simplified the closed form expressions for average symbol error probability. We also characterize the impacts of key parameters Rician factor K and number of elements on IRS on ergodic capacity with CSI and without CSI at the transmitter.

Comments
This work correct the errors in equations (4), (5) of reference [17]. Our ASEP and Capacity expressions are more compact and simplified than in reference [17]. To the best of our knowledge these expressions in eq. (10),(15) and (17) are not available in the literature. Literature does not consider capacity analysis with CSI at transmitter for RIS aided communication equation (17)
