The space characteristics of the physical channels are utilized reasonably. Accordingly, a beam gain is obtained, interference is suppressed effectively, and the apparatus is easy to operate.

Method and apparatus for down-link feedback multiple antenna transmission in wireless communication system

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()=Coeff()+&#x3b1;Coeff(&#x2212;1);and outputting the digital beam output signal corresponding to the maximum correlation coefficient.
