    Abstract: PURPOSE: An exchange interleaver realizing method is provided to be capable of satisfying a distance-limited condition value and securing a sufficient random characteristic, even though the size of an interleaver is large. CONSTITUTION: A block interleaver of N is constituted so that a difference between a row and a column is minimized(301), and different random integers(i1,i2) are generated(302). Each of the integers is more than or identical to a zero and less than N. Positions of i1 and i2 interleaver values are exchanged(303). Whether a distance-limited condition value(S) is satisfied with regard to the exchanged interleaver values is checked(304). If not, the positions of the i1 and i2 interleaver values are recovered originally and the procedure goes to the 302 step. If so, whether two interleaver values are sufficiently exchanged is checked(306). If not, the procedure goes to the 302 step. If so, the procedure is ended.
