IMPROVED SPATIAL SMOOTHING METHOD FOR GENERATING AN AUTOCORRELATION MATRIX OF RADIO SIGNAL MEASUREMENT VALUES

Abstract: a method for providing an autocorrelation matrix of measurement values of wireless signals between a first and a second object for determining at least one property of the signal propagation of the wireless signals between the first and the second object having f, frequency measurement value vectors, each frequency measurement value vectors having a coordinates with a>=1 and with f>1 which are provided. an autocorrelation matrix with a frequency vector number smaller than f is formed from the set of frequency measurement value vectors by means of spatial smoothing for performing spatial smoothing, a plurality of subspace matrices each having a number of frequency measurement value vectors are formed and wherein the subspace matrices are each correlated with themselves and the subspace matrices correlated with themselves are added up.
