On the Performance of Analytical Channel Models in Capturing Channel Correlation Structure

This paper investigates the capabilities of analytical MIMO channel models in correctly capturing the underlying correlation structure of geometrically-based channel structures. The limitations and performance differences of two correlation-based analytical models, the Kronecker model and a structured eigenbasis model are examined. Additional insight into the limitations of using either model in accurately predicting system performance is provided through an examination of common channel metrics and the impact of modeling mismatch on those metrics.
