Estimation of Statistical Properties in a Mobile MIMO System

Abstract: Several measures to evaluate the stationarity of a MIMO radio channel are proposed and implemented. The analysis is performed on a Kronecker model implementation of the channel matrix covariance, which describes the statistical characteristics and transmission properties of the radio channel. The analysis involves calculating the Path Gain, Eigen Quotient and Correlation Matrix Distance. A novel measure, Time of Stationarity, is introduced based on the CMD and is seen to correlate with changes in the Eigen Quotient.
