Claim 16:
17. The method of claim 13, wherein in the optimal precoding vector detection step, detecting the optimal precoding vector from among the precoding vectors included in the pre-stored codebook using the estimated channel information is performed by the following (Equation 6),
wherein the optimal precoding vector is a precoding vector that allows the receiver to receive the transmission signal from the transmitter with the highest power,, i
      opt
     
     =
     
      
       argmax
       i
      
           
    
   
   
    
     (
     
      Equation
      ⁢
