Abstract
In this paper, the effect of spatial smoothing on performance of widely used stochastic narrowband multiple-input multiple-output (MIMO) radio channel model, namely the Kronecker model, is investigated based on data measured in urban microcellular environment at 5.3 GHz carrier frequency. Results from non-line of sight (NLOS) and line of sight (LOS) traveling routes are analyzed. It is noticed that in NLOS traveling route spatial smoothing improves the accuracy of the large eigenvalues of the channel correlation matrix and significantly enhances the applicability of the Kronecker structure. Under LOS condition both the Kronecker model and its smoothed version fail to render the eigenvalues of the measured channel correlation matrix but spatial smoothing slightly improves the applicability of the Kronecker structure.
