An apparatus for generating indexes of an interleaver for input data comprises: a main processor for calculating an index for a predetermined bit of the input data; and an index operator for receiving the index calculated by the main processor, calculating in parallel indexes for bits after the predetermined bit, and deriving a plurality of indexes. The main processor calculates the index for ito (i+15)bits of the input data where i is an integer equal to or larger than 0, and transfers a result of (128*f)modK to the index operator. The index operator calculates an index for an (i+j+16)bit where j is an integer which satisfies 0&#x2266;j&#x2266;7 by using an equation of &#x3a0;(i+j+16)=(2*&#x3a0;(i+j+8)&#x2212;&#x3a0;(i+j)+128*f)modK where K is a size of the input data and fis a coefficient calculated from K.
