Multiple-input multiple-output (MIMO) systems can be considerably afflicted by uncertainty and numerical errors from various sources at different stages in the modeling and simulation process. In this paper, we perform a verification and validation analysis of the process for frequency selective MIMO systems and establish the respective current verification degree for the subtasks. Our special focus is on the stage of channel estimation, for which we show in detail how the verification degree can be improved using methods with result verification and analyse the uncertainty using Monte-Carlo and interval techniques. However, we also touch upon the stages of channel simulation and power allocation from the same point of view.
