This paper deals with the problem of the design of the phase shift matrix for reconfigurable intelligent reflecting surface (RIS). The design problem takes into consideration non-ideal channel estimation, limited analog to digital (ADC) resolution at the base station (BS), and phase noise at the RIS. The RIS is deployed to serve users in the dead zone blocked by some obstacle. The proposed method for optimizing the phase shift matrix is dependent on the statistical properties of the channel that is known to change over larger time spans consisting of several coherence periods. Numerical analysis shows large gains in terms of sum throughput, also we show that the limited ADC resolution has a larger degradation impact on performance in comparison to the phase noise.
