Simulation and Measurement Based Correlation Estimation for Ultra Wideband Antenna Arrays

In order to optimize the performance of diversity antenna systems for communications applications it is desirable to have little correlation between the signals at the different receiving antennas. This paper deals with the estimation of the correlation coefficients of a linear ultra wideband antenna array in an indoor propagation scenario. A suitable approach for the estimation procedure is described and applied to propagation simulation results as well as to measurement results. Correlation coefficients obtained from the proposed estimation procedure are compared to analytically calculated correlation coefficients in order to verify the estimation procedure.
