Abstract

A spatial domain matched filtering method and an array receiver in a radio communication system are provided. The spatial domain matched filtering method includes the steps of: receiving array digital signals; weighting the array digital signals to obtain digital beam output signals; evaluating power value of digital beam output signals and normalizing the digital beam output signals; evaluating a correlation coefficient reflecting the energy of an expected signal in each beam; wherein evaluating equations are: <MATH> Coeffi(k)=Coeffi(k)+ alpha Coeffi(k-1); and outputting the digital beam output signal corresponding to the maximum correlation coefficient. <IMAGE>
