<p>PURPOSE: A code book selection method in a multiple input-output system and an apparatus thereof for minimizing packet error rate are provided to select a precoding matrix for maximizing signal to noise ratio using a V-BLAST/D(V-BLAST with decoding) method. CONSTITUTION: A code book selection method in a multiple input-output system and an apparatus thereof for minimizing packet error rate are as follows. The channel information is estimated from receiving signal(303). An order of each multi-level hierarchy is determined by performing channel arrangement(305). Signal to ratio of the channel is calculated about precoding matrix within a code book(307). The precoding matrix is selected for maximizing the signal to ratio with minimum value.</p> |
