摘要： 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: Coeff i ⁡ ( k ) = 1 N ⁢ ∑ n = 1 N ⁢ || 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.
