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:Coeffi⁡(k)=1N⁢∑n=1N⁢||S~Bi⁡(n)⁢s*⁡(n)⁢||2,Coeffi(k)=Coeffi(k)+αCoeffi(k−1);and outputting the digital beam output signal corresponding to the maximum correlation coefficient.
